To determine if any correlation exists with incidence of nutrient canals in subjects with underlying systemic illness. 50 subjects were selected, which includes ten diabetic subjects, tenhypertensive subjects, ten post-menopausal women, ten periodontitis subjects,and ten subjects without any underlying systemic illness as control group.Radiovisiograph of all the patients was taken for evaluation of nutrient canals. Statistical analysis ofthe data was done using the statistical package for the social sciences (SPSS 16.0) using ANOVAanalysis. Differences were considered significant when P ≤ 0.05. Among50patients, 41 patientsshowed nutrient canals, whereas ninepatients didn’t show nutrient canals. Seven oftenpatients in Group I showed nutrient canals that accounts to 70% prevalence, eightof ten patients in Group IIshowed nutrient canals that account to 80% prevalence, and eightof ten patients in control group showednutrient canals that account to 80% prevalence and eight of ten patients in group V showed nutrient canals that account to 80% prevalence. Incidence of nutrient canals (NC) in the periapical radiograph can act as a supplemental diagnostic aid in detection of underlying systemic conditions like hypertension, diabetes mellitusand aiding the patient in his/her overall health and treatment planning

It is anticipated that Japanese quail /Coturnix coturnix japonica/ will provide animal proteins in long term space flights. Consequently this species of birds is of research interest of international space program INTERCOSMOS. In the year 1987 we reported on an experiment /2/ in which the effect of chronic acceleration of 2 G hypergravitation, the hypodynamy and the simultaneous effect of chronic acceleration and the location in the centre of the turntable of the centrifuge on the protein fractions in skeletal muscles was studied. The ultrastructure of the heart muscle was now in this experiments examined as well.Japanese quail cockerels, aged 48 days were exposed to 2 G hypergravitation /group IV/ in a 6,4 m diameter centrifuge, to hypodynamy /group III/ and their combination /group V/, respectively for 6 days / Fig.1/. The hypodynamy in group III was achieved by suspending the birds in jackets without contact the floor. The group II was located in the centre ofthe turntable of the centrifuge. The control group I. was kept under normal conditions. The quantitative ultrastructure of myocard was evaluated by the methods of Weibel/3/ - this enables to determine the number, relative size and volume of mitochondria volume of single mitochondria, defficiency of mitochondrial cristae and volume of myofibrils.

AbstractHuman beta defensins (hBDs) may play an important role in the progression of lichen sclerosus (LS), due to their ability to induce excessive stimulation of extracellular matrix synthesis and fibroblast activation. The genetic ability of the individual to produce defensins, the presence of microbes influencing defensin production, and the sensitivity of microbes to defensins together regulate the formation of an ever-changing balance between defensin levels and microbiome composition. We investigated the potential differences in postmenopausal vaginal microbiome composition and vaginal hBD levels in LS patients compared to non-LS controls. LS patients exhibited significantly lower levels of hBD1 (p = 0.0003), and significantly higher levels of hBD2 (p = 0.0359) and hBD3 (p = 0.0002), compared to the control group. The microbiome of the LS patients was dominated by possibly harmful bacteria including Lactobacillus iners, Streptococcus anginosus or Gardnerella vaginalis known to initiate direct or indirect damage by increasing defensin level production. Our observations highlight that correcting the composition of the microbiome may be applicable in supplementary LS therapy by targeting the restoration of the beneficial flora that does not increase hBD2-3 production.

Pyrethroid cyhalothrin (PC) is an insecticide that is used worldwide for pest control in agriculture and household use. Samoa extract (SE) is a potent antioxidant protecting cells from oxidative stress. The present study investigates the protective and therapeutic effect of SE on PC-induced changes in sperm quality in male rats. Fifty adult male albino rats were divided into five groups: group I: served as control; group II: received PC i.p. only (6.2 mg/kg b.wt.); group III: received SE only (100 mg/kg b.wt., p.o.) for eight weeks; group IV: received SE as a protective agent daily for eight weeks, then followed by the administration of PC (i.p.) three times a week for two weeks; group V: exposed to PC (i.p.) three times a week for two weeks, then treated with the SE daily for 8 weeks. Results showed that PC caused markedly impaired sperm quality (a count, viability, motility, and abnormality). Compared to PC-treated animals, SE in the protective group markedly restored the alteration of sperm indices. However, SE in the curative group was found to be less effective in restoring PC-induced alterations. In conclusion, the data of this study revealed that the SE as a protective agent is more effective than as a therapeutic agent. Keywords: Samoa; Pyrethroid; Sperm quality; Rat

Abstract Introduction: Equol, an isoflavone derivative whose chemical structure is similar to estrogen, is considered as a potentially effective agent for relieving climacteric symptoms, for the prevention of the lifestyle-related diseases, and for aging care in post-menopausal women. We investigated the effect of an equol-containing supplement on metabolism and aging, and climacteric symptoms, with respect to internally-produced equol in post-menopausal women.Methods: A single center, randomized controlled trial (registration number: UMIN000030975) on 57 post-menopausal Japanese women (mean age: 56±5.37 years), was conducted. Twenty-seven women received the equol supplement, while the remaining received Control. Metabolic and aging-related biomarkers were compared before and after the 3-month intervention. Climacteric symptoms were assessed every month using a validated self-administered questionnaire in Japanese post-menopausal women. Results: Three months post intervention, the treatment group showed significant improvement in climacteric symptoms, when compared to the Control group (81% vs. 53% respectively, p=0.045). We did not observe any beneficial effect on metabolic and aging-related biomarkers in the intervention group. However, in certain populations significant improvement in skin auto-fluorescence, which is a measurement of AGE skin products, and visceral fat area was observed, especially among equol producers. Conclusion: Women receiving equol supplement showed improved climacteric symptoms. This study offered a new hypothesis that there may be a synergy between supplemented equol and endogenously-produced equol to improve skin aging and visceral fat in certain populations.

AbstractRecent evidence suggests that Ca supplements increase the risk of cardiovascular events, but the mechanism(s) by which this occurs is uncertain. In a study primarily assessing the effects of various Ca supplements on blood Ca levels, we also investigated the effects of Ca supplements on blood pressure and their acute effects on blood coagulation. We randomised 100 post-menopausal women to 1 g/d of Ca or a placebo containing no Ca. Blood pressure was measured at baseline and every 2 h up to 8 h after their first dose and after 3 months of supplementation. Blood coagulation was measured by thromboelastography (TEG) in a subgroup of participants (n 40) up to 8 h only. Blood pressure declined over 8 h in both the groups, consistent with its normal diurnal rhythm. The reduction in systolic blood pressure was smaller in the Ca group compared with the control group by >5 mmHg between 2 and 6 h (P≤0·02), and the reduction in diastolic blood pressure was smaller at 2 h (between-groups difference 4·5 mmHg, P=0·004). Blood coagulability, assessed by TEG, increased from baseline over 8 h in the calcium citrate and control groups. At 4 h, the increase in the coagulation index was greater in the calcium citrate group compared with the control group (P=0·03), which appeared to be due to a greater reduction in the time to clot initiation. These data suggest that Ca supplements may acutely influence blood pressure and blood coagulation. Further investigation of this possibility is required.

Abstract Introduction The aim of obturation in the root canal is to completely seal the canal space to eliminate all the portals of entry and exit between root canal and periodontal space. Various techniques have been developed to achieve a hermetic seal. Materials and Methods As many as 150 extracted human maxillary central incisors were taken for the study. Biomechanical preparation was done up to F5 protaper file. According to different obturation techniques, samples were divided into six groups, keeping 30 samples in experimental and 15 samples in control groups. Group I–Lateral Condensation, Group II–Thermafil, Group III–Beefill, Group IV–GuttaFlow, Group V–Positive Control group, Group VI–Negative Control group. After obturation, the samples were immersed in 2% Rhodamine-B dye for 24 hours. Each sample was longitudinally sectioned to examine under confocal laser scanning microscope. Statistical Analysis The results were evaluated with ANOVA and posthoc Tukey honest significant difference (HSD) comparison test. Results The mean values of dye penetration of different groups were Group I (Lateral Condensation) 1.51 ± 0.451, Group II (Thermafil) 0.918 ± 0.399, Group III (Beefill) 1.30 ± 0.559. Group IV (GuttaFlow) 0.655 ± 0.396, Group V (Positive Control group) 1.96 ±0.046, Group VI (Negative Control group) 0 ± 0. The lowest mean value of apical microleakage was found in GuttaFlow amongst all experimental groups. Conclusion It can be concluded that the GuttaFlow obturating material exhibited better apical sealing ability with canal walls.

PURPOSE: To determine the effects of green propolis extracted in L-lysine (WSDP) and of L- lysine for 40 weeks on induced rat bladder carcinogenesis. METHODS: The animals (groups I, II, III, IV, V and VI) received BBN during 14 weeks. Group I was treated with propolis 30 days prior received BBN, and then these animals were treated daily with propolis; Groups II and III was treated with subcutaneous and oral propolis (respectively) concurrently with BBN. The animals of Group IV were treated L-lysine; Group V received water subcutaneous; and Group VI received only to BBN. Among the animals not submitted to carcinogenesis induction, Group VII received propolis, Group VIII received L-lysine and Group IX received water. RESULTS: The carcinoma incidence in Group I was lower than that of control (Group VI). The carcinoma multiplicity in Group IV was greater than in Group VI. All animals treated with L-lysine developed carcinomas, and they were also more invasive in Group IV than in controls. On the other hand, Group VIII showed no bladder lesions. CONCLUSION: The WSDP is chemopreventive against rat bladder carcinogenesis, if administered 30 days prior to BBN , and that L-lysine causes promotion of bladder carcinogenesis.

The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and sulfasalazine in combination with herbal medicine on dextran sodium sulfate- (DSS-) induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n=9): Group I (normal group), Group II (DSS control group), Group III (DSS + sulfasalazine (30 mg/kg)), Group IV (DSS + sulfasalazine (60 mg/kg)), and Group V (DSS + sulfasalazine (30 mg/kg) + Cinnamomi Cortex and Bupleuri Radix mixture (30 mg/kg) (SCB)). Colonic pathological changes were analyzed using hematoxyline/eosin staining. The antioxidant, inflammatory, and apoptotic protein levels were determined using western blotting. SCB supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SCB treatment significantly reduced the expression of proinflammatory signaling molecules through suppression of both mitogen-activated protein kinases (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways and prevented the apoptosis of the colon. Moreover, SCB administration significantly led to the upregulation of antioxidant enzymes including SOD and catalase. Taken together, SCB treatment might offer a better treatment for human UC than sulfasalazine alone or may be useful as an alternative therapeutic strategy against UC, without any evidence of side effects.

The objective of this study is to investigate the functions of parotid and pancreatic glands in response to intoxication with parathion-methyl (PM) and the effects of treatment in rats. Seventy-five male Wistar rats were divided equally into five groups: Group I, control; group II, received atropine and pralidoxime (2-PAM) for 24 h, but no PM; group III, oral PM but no atropine and 2-PAM; group IV, PM and atropine for 24 h and 2-PAM; group V, PM and atropine for 96 h and 2-PAM. After the administration of the chemicals, blood samples were drawn to test for amylase, lipase, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE), while pancreatic and parotid glands of each rat were removed for light microscopic examination. Amylase levels were found significantly elevated in groups II, III, IV, and V, whereas lipase levels were supranormal in groups III, IV, and V. The blood levels of AChE were decreased in groups III and IV and BChE were decreased in II, III, IV, and V. No evidence of pancreatitis and parotitis was identified in the histopathologic evaluation in any group in 96 h; however, hyperchromasia, irregularity in nuclei, and binuclear cells were observed in all parotid glands in group V. Parotitis and pancreatitis were not evident; however, hyperamylasemia and hyperlipasemia were found, whereas various histologic changes in parotid glands were documented in the groups that were administered organophosphate and treatment.
