Abstract Background and purpose Studies in the animal models of epilepsy have suggested the anti-seizure effects of neuroactive steroids and its derivatives in kainic acid and pilocarpine induced limbic seizures and status epilepticus in mice, but no such studies have been reported in the published literature on the role of allopregnanolone in chemical kindling model and its interaction with sodium valproate. The purpose of this study was to evaluate the interaction between sodium valproate and allopregnanolone in pentylenetetrazole induced kindling model in rats. Methods In a PTZ kindled Wistar rat model, sodium valproate and allopregnanolone were administered 30 min before the PTZ injection. The PTZ injection was given on alternate day till the animal became fully kindled or till 10 weeks. The parameters measured were latency to develop kindling and incidence of kindling, histopathological study of hippocampus, hippocampal anti-oxidant parameters and hippocampal DNA fragmentation studies. Results In this study, the combination of low dose of allopregnanolone with low dose of sodium valproate showed a similar beneficial effect to that of a higher dose of sodium valproate in significantly reducing the number of kindled animals (0/8) as compare to PTZ control group (5/8) as well as the seizure scores and the histopathological scores. The combination significantly reduces oxidative stress by significantly decreasing the MDA levels, and increasing the SOD levels and GSH levels in the hippocampus of rats as compared to PTZ control group. So all these data suggest the antiepileptic effect of the combination and confers the synergistic interaction between the allopregnanolone and sodium valproate. Conclusions It can be concluded that by choosing this combination the dose of sodium valproate can be reduced and thereby reduces the incidence of adverse effects caused by sodium valproate and hence proves to be a useful combination clinically. This study has lead the basis to further investigate the various combinations of neurosteroids and valproate in the process of epileptogenesis with better side effect profile.

Cell proliferation and apoptosis in the remnant rat kidney after treatment with lowdose irradiation was investigated. Material and methods. In the first group (n=9), adult male Wistar rats underwent 5/6 nephrectomy (NPX); in the second group (n=9), NPX was combined with low-dose irradiation. Rats without surgery and irradiation formed the control group (n=9). Results. Hypertension and proteinuria induced by NPX were decreased by 3-Gy irradiation. The 5/6 NPX rats showed a dramatic increase in proliferating and apoptotic cells in the glomeruli and in the distal tubules at week 2, which was significantly decreased by low-dose irradiation. Conclusion. The data demonstrate that low-dose irradiation is a factor slowing the process of chronic renal injury.

The study was aimed at determining the effect of aqueous extract of Theobroma cacao on the histology of the ovary of female albino wistar rat. Twenty-four (24) adult wistar female rats weighting about 100- 160g were used for this research work and were divided into three (3) groups of eight (8) animals each. Group A; control, Group B; low dose and Group C; high dose with eight (8) animals in each group. Control group received vital feed; the low dose group was administered 240mgkg body weight of Theobroma cacao extract and the high dose group was administered 500mgkg body weight of the test substance. Extract was given daily by oral gavage method for twenty-one (21) days. Twenty-four hours after the last administration, all animals in each group were sacrificed under chloroform anesthesia. The ovaries were harvested, weighed and fixed in 10% buffered formalin for histological studies. Results showed that following administration of extract of Theoboma cacao at these doses, an insignificant decrease in organ weight was observed. Histological observation showed few follicles as well as loss of the substance of granulose cell this could possibly suggest decrease in production of sex steroids in the ovary.Keywords: Theobroma Cacao, Ovary, Histology

Aims: The aim of this study was to evaluate the anti-diabetic, hepatorenoprotective and antilipidemic potentials of Syzygium aromaticum (clove) in albino rats. Study Design: This study is a non-randomized experimental study. Place and Duration of Study: Department of Medical Laboratory Technology, University of Port Harcourt, Nigeria, between September, 2019 and December, 2019. Methodology: Thirty-five male Wister rats with weight between 145 to 150 g were randomly selected into seven groups of five rats each. The first group served as Negative control (group 1). The second group was the positive control (Diabetic group). The remaining five groups being the treatment groups (3-7). Diabetes was induced intraperitoneally with 65 mg/kg of streptozotocin (STZ) single dose. Group 3 Diabetic group treated with metformin (100 mg/kg); Group 4 Diabetic group treated with low dose clove (250 mg/kg). Group 5 Diabetic group treated with low dose clove and metformin; Group 6 Diabetic group treated with high dose clove (750 mg/kg), while Group 7 were Diabetic group treated with high dose clove (750 mg/kg) and metformin for six weeks. Blood samples were collected via cardiac puncture in appropriate EDTA, heparinized and sterile bottles for standard laboratory investigations of lipid profile, glucose, liver enzymes, urea and creatinine. Plasma lipid profile, liver enzymes, urea and creatinine were determined using enzymatic end point method under standard operating procedures. Statistical analysis was done using Graph Pad Prism Version 5.03 and p values less than 0.05 were considered statistically significant. Results: Results revealed that the STZ-induced diabetic group exhibited highly significant increase in activity of liver enzymes AST, ALT and ALP, increase in the levels of urea, creatinine, glucose and most lipid profile parameters as compared to the negative control group (p<0.001). Histopathological examination of liver and kidney tissues of diabetic rats indicated slight changes. However, their changes were overcame by clove treatment and the majority of the cells tend to be normal. Low dose clove group 5 (250 mg/kg) with metformin decreased the levels of the analytes most when compared to the levels of the positive control group. For glucose, group 5 gave a mean glucose level of 4.40 ± 1.08 mmo/l, significantly lower than the positive control group 39.67 ± 0.67, ALT group 5 gave a mean ALT level of 56.00 ± 7.11, which was significantly lower than the positive control group 205.70 ± 14.79, for urea group 5 gave a mean urea level of 4.25 ± 0.77 which was significantly lower the control group 23.80 ± 3.56  at  p < 0.001, thereby yielding a better treatment result. Conclusion: In conclusion, low dose clove supplementation with metformin could be excellent adjuvant support in the therapy of diabetes mellitus and its complications.

Hemophilia A is an inherited bleeding disorder caused by factor VIII (FVIII) deficiency. In most minor-to-moderate bleeding events, FVIII concentrates therapy can result in significant lifesaving. However, chronic FVIII concentrates therapy can cause FVIII inhibitors synthesis and replacement therapy inefficacious. Immunosuppressive therapy can suppress FVIII inhibitors synthesis and make FVIII concentrates therapy more responsive. This study aims to determine the effects of low-dose methylprednisolone on acquired FVIII inhibitors. A randomized clinical trial was conducted on 11 hemophilia A male patients with high level of FVIII inhibitors. This pretest-posttest study design consists of intervention group (6 patients) who received 1 mg/bodyweight/day methylprednisolone, and control group (5 patients) received 100 mg/day sugar pill placebo for 6 weeks. Statistical analysis used independent t-test and paired t-test. Results showed significant FVIII inhibitors rising in pretest-posttest mean comparison of both intervention group (p = 0.001) and control group (p = 0.001). Further result showed inter-groups pretest mean comparison (p = 0.976) and inter-groups posttest mean comparison (p = 0.034). We conclude that low-dose methylprednisolone significantly suppresses the FVIII inhibitors synthesis pace within 6 weeks instead of inhibits the FVIII inhibitors synthesis.

Potash known as potassium carbonate (K2 CO3 ) is a mixture of salt with other components including impurities which coexist in mineral and salt is highly consumed in various forms by pregnant women. The aim of this research is to evaluate the weight and serum indices of potash on the uterus of pregnant wistar rat with the specific objectives of determining the effect of potash on the progesterone and estrogen level and weight index of pregnant wistar rat. A total of Twenty-five albino Wistar rat with weights ranging from (180-300g) were used and allocated into five groups of five animals each (4 females and a male) designated as groups 1, 2, 3, 4, and 5. The experimental groups 2, 3, 4, and 5 were administered different doses of potash. The animals were allowed for a period of one week for acclimatization under normal temperature (270C -300C) which they were being feed with normal feed (grower’s mash) and water ad libitum for one (1) week. Administration of potash were through the oral route. Group 1 served as the control group and was administered distilled water only. Group 2 received 300mg/kg of potash plus feed and water was given ad libitum for 7 days after detection of pregnancy. Group 3 received 600mg/kg of potash plus feed and water was given ad libitum. Group 4 received 900mg/kg of potash plus feed and water was given ad libitum. Group 5 received 1200mg/kg of potash plus feed and water was given ad libitum. After analysis from histological procedures, the progesterone and estrogen level of pregnant wistar rat were evaluated and observed that treatment with potash induced changes. However, the level of progesterone activities increased in the test groups (2, 3, and 5) when compared to the control group. As for estrogen level, the increased level was observed to be progressive in the test groups, with the highest seen with the 1200mg/kg group as well as the physical activity of the wistar rats. At the end of the study, the results showed that Potash alters progesterone and estrogen level as well as the physical activity of the wistar rats.

Exposure to drugs and toxic chemicals, during late pregnancy, is a common occurrence in childbearing women. Some studies have reported that more than 90% of pregnant women use at least 1 prescription; of this, 60% used more than one. Another study indicated that 80% of the consumed drugs were not prescribed, and of this figure, 95% were “over-the-counter” drugs. Acetaminophen, the safest of all over-the-counter drugs, has been reported to induce fetal liver necrosis in man and animals and to have abortifacient and embryocidal action in mice. This study examines the degree to which acetaminophen affects the neonatal liver and kidney, when a fatty diet is simultaneously fed to the mother during late pregnancy.Timed Swiss Webster female mice were gavaged during late pregnancy (days 16-19) with fat suspended acetaminophen at a high dose, HD = 84.50 mg/kg, and a low dose, LD = 42.25 mg/kg; a control group received fat alone.

Abstract. The aim of this study is to evaluate the effect of α-tocopherol supplementation at two doses (600 and 1200 mg × kg–1) on kidney antioxidant status and the histopathological changes in Wistar rats after 12 weeks of exposure at different diets. Forty rats has been divided into 4 groups of 10 rats each, the control group received basal diet with 5 % fresh sunflower oil (FSO), the second group: 5 % oxidized sunflower oil (OSO), the third group: 5 % OSO supplemented with 600 mg × kg–1 α-tocopherol and the fourth group: 5 % OSO supplemented with 1200 mg × kg–1 α-tocopherol. In OSO groups, the results showed highly significant increases of LPO (from 31.3 ± 0.9 to 53.8 ± 1.2 nmol of MDA formed/min/mg protein, p < 0.0001) with a significant decrease (p < = 0.001) of the antioxidant enzymatic activities (CAT, SOD, GPX, GR and G6PDH), body weight (339 ± 9 to 290 ± 3 g) and α-tocopherol levels (13.6 ± 0.6 to 6.5 ± 0.4 μg/mg protein). In OSO groups with 600 mg × kg–1 α-tocopherol, an antioxidant effect was found, reflected by a return of the parameters to values similar to those of the control group. However, higher doses of α-tocopherol (1200 mg × kg–1) induced a depletion of antioxidant status, α-tocopherol levels (6.0 ± 0.3 μg/mg protein, p < 0.001) and a very highly significant rise (p < 0.0001) of LPO content (54.86 ± 0.01 nmol of MDA formed/min/mg protein). The kidney tissues also showed changes in glomerular, severe inflammatory cells infiltration, and formation of novel vessels. So, we can conclude that the oxidative stress is attenuated by a moderate administration of 600 mg × kg–1 α-tocopherol, while a pro-oxidant effect occurs at 1200 mg × kg–1 α-tocopherol.

SummaryThe effect of subcutaneous low-dose heparin on postoperative deep-vein thrombosis (D. V. T.) (diagnosed by the 125I-labelled fibrinogen test) has been investigated in a trial of 143 patients undergoing the operation of total hip replacement. Two randomized studies were carried out: in one the scanning for D.V.T. was carried out daily for 7 days post operatively and in the other for 15 days. In both, the incidence of D.V.T. was significantly lower in the heparin-treated patients (P<0.005). Bilateral D.V.T. was also prevented (P<0.05), through the extension of D.V.T. to the distal veins of the thigh was not significantly reduced. Heparin treatment was, however, followed by a higher incidence of severe postoperative bleeding (P< 0.02) and wound haematoma formation (P< 0.005), and the postoperative haemoglobin was significantly lower than in the control group (P<0.005). A higher number of transfused blood units was also needed by the heparin treated patients (P<0.001).

Introduction: Atrophic vaginitis is a common problem in postmenopausal women and results from decreased levels of blood estrogen. It is associated with symptoms of itching, burning, dyspareunia, and postmenopausal bleeding. The present study evaluated the effects of fenugreek extract on atrophic vaginitis. Materials and Methods: This randomized controlled clinical trial was performed on 60 postmenopausal women in Ardabil, Iran, in 2018. The participants were selected using block randomization with the allocation ratio 1:1. Those in the intervention group received 0.5g (the applicator filled to the half-full mark) fenugreek vaginal cream 5% twice a week for 12 weeks. The control group received conjugated estrogens vaginal cream at the dose of 0.625 mg (the applicator filled to the half-full mark) containing 0.3 mg of conjugated estrogens. Atrophic vaginitis was evaluated before and after the treatment through clinical examination, clinical signs, and measurement of Vaginal Maturation Index (VMI). Findings: After the 12-week intervention and modification of the baseline score, the mean (standard error) score for atrophic vaginitis signs was 3.100 (1.43-4.75). This difference was statistically significant in intragroup comparison and in favor of the control group in intergroup comparison (p=0.001). VMI was less than 49% in 86.7% and 46.7% of the participants in the intervention and control groups, respectively. This was a significant difference in favor of the control group (p=0.001). Conclusion: The results of this study showed that total fenugreek extract could be effective in treating signs of atrophic vaginitis, but it was not as effective as ultra-low-dose estrogen.
