The sex differences of infection and inflammatory diseases particularly appear at reproductive age and depend on the sex hormone level, varied between male and female. There are a few sets of data about the sex differences of infection and inflammatory diseases course, including systemic inflammatory response syndrome (SIRS) and sepsis, of newborns. The aim of our research was the estimation of morphological and immunological manifestation of SIRS of the newborn Wistar rats. Investigations were carried out on male and female two-day-old Wistar rats (10–12 g). SIRS was modeled by intraperitoneal injection of LPS (E. coli, O26: B6 strain, Sigma) in high dose—15 mg/kg. We did not find out any sex differences of the liver lesions severity between newborn males and females after LPS injection. The levels of endotoxin and estradiol in the serum, as the number of neutrophils in the intra-alveolar septa of the lungs, were higher in males than females with SIRS. Production of IL-2 and TNF-α by the spleen cells of males was higher than that in control group that reflects polarization predominantly on the Th1-type immune response. The secretion of IL-2, TNF-α, and IFN-γ by ConA activated spleen cells of females decreased that reflects the suppression of Th1-type immune response. We suppose that the LPS administration in the high dose causes the multidirectional reaction of the immune system of neonatal males and females Wistar rats.

Background and purposeThe therapeutic potential of different stem cells for ischaemic stroke treatment is intriguing and somewhat controversial. Recent results from our laboratory have demonstrated the potential benefits of human umbilical cord blood-derived mesenchymal stem cells (MSC) in a rodent stroke model. We hypothesised that MSC treatment would effectively promote the recovery of sensory and motor function in both males and females, despite any apparent sex differences in post stroke brain injury.MethodsTransient focal cerebral ischaemia was induced in adult Sprague-Dawley rats by occlusion of the middle cerebral artery. Following the procedure, male and female rats of the untreated group were euthanised 1 day after reperfusion and their brains were used to estimate the resulting infarct volume and tissue swelling. Additional groups of stroke-induced male and female rats were treated with MSC or vehicle and were subsequently subjected to a battery of standard neurological/neurobehavioral tests (Modified Neurological Severity Score assessment, adhesive tape removal, beam walk and rotarod). The tests were administered at regular intervals (at days 1, 3, 5, 7 and 14) after reperfusion to determine the time course of neurological and functional recovery after stroke.ResultsThe infarct volume and extent of swelling of the ischaemic brain were similar in males and females. Despite similar pathological stroke lesions, the clinical manifestations of stroke were more pronounced in males than females, as indicated by the neurological scores and other tests. MSC treatment significantly improved the recovery of sensory and motor function in both sexes, and it demonstrated efficacy in both moderate stroke (females) and severe stroke (males).ConclusionsDespite sex differences in the severity of post stroke outcomes, MSC treatment promoted the recovery of sensory and motor function in male and female rats, suggesting that it may be a promising treatment for stroke.

Abstract Moringa oleifera (MO) is a widely used as the nutritious and non-traditional feed supplementation containing kinds of bioactive substances. However, the enhancement effect of Moringa oleifera leaf Polysaccharide (MOLP) as a feed additive in broilers growth performance and immunity remains unclear. In this study, MOLP was obtained by water extraction and alcohol precipitation method, then purified with Trichloroacetic acid (TCA) assay. Chickens were randomly divided into 4 groups, to receive different doses of MOLP (0, 0.1, 0.2, 0.4g/kg) in feed for 3 weeks. The body weight gain (BWG) and feed consumption were recorded for feed conversion ratio (FCR) and average daily feed intake (ADFI) calculation. Broiler chickens were sacrificed and sampled on day 14, 21, 28 (D 14, D 21, and D 28) respectively. Serological indicators, including total protein (TP), albumin (ALB), globulin (GLO), and creatinine (CREA) were detected. ELISA kits were applied for detecting the levels of immunoglobulin A (IgA), immunoglobulin G (IgG), interleukin-2 (IL-2), and tumor necrosis factor (TNF-α). From D 21 to D 28, the results showed that middle dose of MOLP significantly increased BWG and ADFI as well as liver and bursa indexes when compared with the control group. In addition, TP and GLO were also increased (P<0.05). All MOLP treatments enhanced the serum concentrations of IgG and IL-2 (P<0.01). Furthermore, results of quantitative RT-PCR showed that high dose of MOLP treatment significantly increased (P<0.001) the mRNA expression levels of IL-2 and TNF-α of chickens relative to the control group. In conclusion, the results showed that MOLP supplementation contributed to improve growth performance and immune response in broiler chickens, and MOLP could be considered as a promising feed additive.

Differences between male and female guilt reactions to hypothetical guilt-inducing situations of a sexual, hostile, and moral nature were investigated. Two independent samples of Ss (56 men, 56 women; and 34 men, 62 women) reported the intensity of their anticipated guilt reactions to 60 hypothetical behavior situations presented in sentence-completion format through the use of scaled response alternatives. Across both samples there were specific behaviors in which stable sex differences were evidenced, i.e., females' reactions were more intense for those behaviors reflecting sexual transgressions. However, males and females were highly similar in their reactions to hostile and moral guilt-provoking situations. Implications of these results for research on trait-guilt were discussed.

Anxiety Depression

Background: Early life stress (ELS) models such as maternal deprivation (MD) are used to in¬vestigate behavioral changes in rodents under stressful situations. MD is a situation in which rat pups are separated from the dam; MD has different paradigms. The purpose of this research is to evaluate the effects of maternal deprivation on anxiety, depression, and empathy in adult Wistar rats. Materials and Methods: MD was applied to pups as per specifically designed protocol to compare rats of the control group with maternal deprivation rats and also the group, which faced novel objects. Each group consisted of eight rats. In this study, separation started from postnatal day (PND) 14 for various periods up to PND 60. EPM test was undertaken to measure anxiety; moreover, FST was used to indicate levels of depression. Also, changes in the empathy ratio were also demonstrated. One-way analysis of variance (ANOVA), Tukey’s post hoc analysis, and t-test were applied to analyze the results. Results: MD-treated rats showed a significant decrease in anxiety and empathy indexes compared with those in the control group (P<0.05). However, MD significantly increased depression in both male and female rats (P<0.05). Final¬ly, exposure to novel objects decreased depression but did not have any effect on anxiety and empathy levels in MD rats (P<0.05). Conclusion: ELS may lead to various states of mood and behavior in adulthood. According to the findings of this study, depression increases due to MD, though both anxiety and empathy decrease in both male and female Wistar rats. Moreover, ex¬posure to novel objects decreases depression, while anxiety and empathy do not change signifi¬cantly with exposure to novel objects. [GMJ.2019;8:e1093]

Rod And Frame

402 males and 160 females hospitalized for treatment of alcoholism were tested in a standardized manner on the Rod-and-frame test as a means of supplementing an earlier report of normative data on perceptual style among male alcoholics. When their performance was contrasted with that of normal and psychiatric samples, alcoholics were clearly the most field dependent of all groups studied. Statistically significant sex differences justify the need for separate norms for males and females.

Glutamine is the most abundant amino acid in the body and is extensively taken up in gut and liver in healthy humans. To determine whether glucocorticosteroids alter splanchnic glutamine metabolism, the effect of prednisone was assessed in healthy volunteers using isotope tracer methods. Two groups of healthy adults received 5-h intravenous infusions of l-[1-14C]leucine and l-[2H5]glutamine, along with q. 20 min oral sips of tracer doses of l-[1-13C]glutamine in the fasting state, either 1) at baseline (control group; n = 6) or 2) after a 6-day course of 0.8 mg·kg−1·day−1 prednisone (prednisone group; n = 8). Leucine and glutamine appearance rates (Ra) were determined from plasma [1-14C]ketoisocaproate and [2H5]glutamine, respectively, and leucine and glutamine oxidation from breath 14CO2 and 13CO2, respectively. Splanchnic glutamine extraction was estimated by the fraction of orally administered [13C]glutamine that failed to appear into systemic blood. Prednisone treatment 1) did not affect leucine Ra or leucine oxidation; 2) increased plasma glutamine Ra, mostly owing to enhanced glutamine de novo synthesis (medians ± interquartiles, 412 ± 61 vs. 280 ± 190 μmol·kg−1·h−1, P = 0.003); and 3) increased the fraction of orally administered glutamine undergoing extraction in the splanchnic territory (means ± SE 64 ± 6 vs. 42 ± 12%, P < 0.05), without any change in the fraction of glutamine oxidized (means ± SE, 75 ± 4 vs. 77 ± 4%, not significant). We conclude that high-dose glucocorticosteroids increase in splanchnic bed the glutamine requirements. The role of such changes in patients receiving chronic corticoid treatment for inflammatory diseases or suffering from severe illness remains to be determined.

Qualitative and quantitative assessment of microbes making the microbiocenosis of genital tract in women with inflammatory and proliferative diseases of cervix using Femoflor-16 test was the aim of the research. Scrapings of cervix and vaginal fornix in 100 women of reproductive age with cervicitis, vaginitis and in 31 women with cervical pseudoerosion (ectropion) were studied. The control group consisted of 35 relatively healthy women preparing for pregnancy. Cervical and vaginal dysbiosis was found in women with inflammatory diseases of cervix in 37.0% of cases, in women with pseudoerosion in 32.2% of cases. These are 3.3 (р&#60;0.005) and 2.8 (р&#60;0.02) times as much as in the group of healthy women preparing for pregnancy (11.1%). Dysbiosis structure was represented primarily by obligate anaerobic agents such as Gardnerella vaginalis, Atopobium vaginae, Eubacterium spp. in association with other opportunistic bacteria that are clinically most significant microorganisms colonizing female genital tract. Mycoplasma and yeast-like fungi of Candida species were found primarily with anaerobes. Aerobic and mixed dysbiosis were only found in 7% of cases in women with inflammatory diseases. Femoflor-16 test is a readily available, fast, efficient, up-to-date method enabling one to begin with early adequate antibacterial therapy and monitor it.

In the present study we analyzed the effect of spironolactone administration on hepatic and intestinal p-nitrophenol-UDP-glucuronyltransferase activity. We used microsomal preparations from male and female Wistar rats to establish whether or not this effect was sex dependent. Enzyme activity was measured in the presence of UDP-N-acetylglucosamine, a presumed physiological activator of the enzyme. Female but not male microsomes showed an increase in enzyme activity of both hepatic and intestinal tissue preparations in response to the inducer pretreatment. In addition, the inducer effect observed in female rats showed a tissue-related difference, since percent increase in the intestinal enzyme activity was greater than that in the liver (127 and 52%, respectively). These results suggest that factors regulating enzyme activity or mechanisms involved in the inducer effect of spironolactone could be different in the intestinal mucosa in comparison to the liver. A possible explanation of sex-related response to spironolactone administration was discussed.Key words: p-nitrophenol, UDP-glucuronyltransferase, spironolactone induction, sex differences.

A study has been made of the length of life, fecundity, oviposition and the effects upon them of adult nutrition in the varied carpet beetle, Anthrenus verbasci (L.).The length of the inactive (unmated) life for males and females at 20°C. and 70 per cent. R.H. was 7·5 and 7·7 days, respectively. This period, which is spent in the moulted last larval skin, decreased with rise in temperature, from a mean of 32·4 days at 10°C. to 3·8 days at 25°C. Humidity differences had relatively little effect.The effects of various diets on the length of life, oviposition cycle and fecundity of active adults were observed. The experimental diets were water, water with pollen, water with albumen, sugar solution, sugar solution with pollen, sugar solution with albumen, and the control group in which the beetles were deprived of food and water. The sugar solution was a mixture of equal parts of glucose, sucrose and fructose in water.There were no differences in length of life between male and female beetles (males 18·2–20·9 days, females 22·1–26·1 days) given water, water with pollen, water with albumen and those deprived of food and water. But there was an increase for both sexes when the beetles were given sugar solution, and a further increase, to a mean of 58·3 days for males and 69·5 for females at 20°C. and 70–90 per cent. R.H., when albumen was added to the sugar solution. However, although sugar solution with pollen increases still further the length of life of the males, that of the females was no different from what it was on sugar solution alone.The preoviposition period ranged from 3–14 days with a mode about the fourth day.The oviposition cycle consisted of three clearly denned peaks of oviposition on about the 6th, 12th and 17th days. There was a similar pattern in all the groups except that those given sugar solution continued to lay, at a low rate, after the end of the third peak.The fecundity of beetles deprived of food and water was 50·3 eggs; for beetles given water, water with albumen and water with pollen there was a significant decrease; for beetles given sugar solution there was an increase which became significant when pollen or albumen were given in addition to the sugar. Maximum fecundity occurred on a diet of sugar solution with albumen.There was significant correlation between length of life and weight on emergence for males given water, water with pollen, or water with albumen, and for females given water with pollen or water with albumen. There was significant correlation between fecundity and emergence weight for females deprived of food and water, given water alone and water with pollen.

Background: Echinochrome (Ech) is the active ingredient in the Histochrome drug, which possesses strong antioxidant, hypolipidemic and hypoglycemic activity. Objective: The present work aimed to characterize the malformations induced by moderate and high dose of Ech during pregnancy. Methods: In this study, eighteen (18) female pregnant rats were assigned into 3 groups (6 rats/ group); control group, low dose Ech (0.1 mg/kg) and high dose Ech (1 mg/kg). Results: The high dose of Ech caused a significant decrease in the number of embryos, uteri weight, body weight gain, placenta weight, and embryo weight and length. Also, the high dose led to a significant increase in serum AST, ALT, ALP, urea and uric acid of mothers. Conclusion: Our findings revealed the first teratogenic effects of high dose Ech. The teratogenic mechanism of Ech works through induction of the hypoglycemic condition in pregnant rats.
