Objective: The objective of this study is to investigate the anti-cataract activity of the aqueous extract of Garcinia indica (AGI) fruit rinds on naphthalene-induced cataract using rats.Methods: Anti-cataract activity of AGI was evaluated using naphthalene model. Rats were divided into five groups (n=6 in each). Naphthalene solution was prepared by dissolving naphthalene in warm corn oil and administered at the dose of 0.5 g/kg/day p.o. for first 3 days and 1 g/kg/day p.o. thereafter for the induction of cataract. Group I normal control received corn oil 5 ml/kg/day. Group II cataract control received naphthalene solution. Group III received Vitamin E 50 mg/kg/day p.o., and Groups IV and V received AGI 200 mg/kg/day p.o and 400 mg/kg/day p.o., respectively, along with the naphthalene solution for 28 days. At the end of the treatment, levels of malondialdehyde, lipid hydroperoxides (LH), carbonyl and sulfhydryl content, and enzymatic and non-enzymatic antioxidants in lens homogenate were measured.Results: Administration of naphthalene produced a mature cataract and an increase in the opacity index. A significant increase in LH and protein carbonyl content while decrease in protein SH content and antioxidant enzymes was found in naphthalene control group as compared to normal control group. Simultaneous administration of AGI and naphthalene delayed the onset and maturation of cataract.Conclusion: The present investigation suggests that AGI protected the lens against naphthalene-induced oxidative damage which might be responsible for delaying the progression of cataract.

This study was carried out to ascertain the hepatotoxic potential of T.daniellii (T.d) and A. cordifolia (A.c). Investigations were conducted using standard methods. Oral administration of 200mg/kg aqueous leaf extracts of T.daniellii caused a non-significant increase in the activity of ALT (5.43±0.60IU/L), AST (16.93±0.26 IU/L) and ALP (160.70±1.04 IU/L) compared to the values recorded on the normal control (group I) ALT (3.84±0.16 IU/L), AST (14.19±0.52 IU/L) and ALP (157.26±0.64 IU/L). Group III administered with 200mg/kg methanolic leaf extract of T. daniellii manifested a significant elevation in the activity of ALT (13.15±0.89 IU/L), AST (22.84±0.38 IU/L) and ALP (170.40±0.44 IU/L) compared to the normal control. Similarly, groups IV and V which were orally administered with 200mg/kg aqueous and methanolic leaf extracts of A. cordifolia showed significant increase in the activity of ALT (6.32±0.33U/L), AST (17.70±0.030U/L) and ALP (161.13±0.09U/L) and ALT (7.55±0.59U/L), AST (19.35±0.26U/L) and ALP (165.38±0.35U/L) respectively compared to the values recorded on the control (group I). In conclusion, drug development protocols involving T. daniellii leaf should preferably use water as an ideal solvent. On the other hand, the hepatotocity associated with both aqueous and methanolic extracts of A. cordifolia could imply the presence of hepatotoxins in the leaf of the said plant.

Doxorubicin-induced cardiotoxicity is the leading cause of morbidity and mortality among cancer survivors. The present study was aimed to investigate the cardioprotective potential of methyl gallate; an active polyphenolic nutraceutical, against doxorubicin-induced cardiotoxicity in Wistar rats. Twenty-four female Wistar rats (150–200 g) were divided into four groups (n = 6) which consist of normal control (group I), doxorubicin control (group II), test-A (group III), and test-B (group IV). Group III and group IV animals were prophylactically treated with methyl gallate 150 mg/kg/day and 300 mg/kg/day orally, respectively, for seven days. Doxorubicin (25 mg/kg; single dose) was administered through an intraperitoneal route to group II, III, and IV animals on the seventh day to induce acute cardiotoxicity. On the 8th day, besides ECG analysis, serum CK, CK-MB, LDH, AST, MDA, and GSH were assayed. Following gross examination of isolated hearts, histopathological evaluation was performed by light microscopy. A significant ( p  < 0.05) cardiac injury, as well as oxidative stress, was observed in doxorubicin control rats in comparison to normal control rats. Methyl gallate at both the doses significantly ( p  < 0.05) reduced doxorubicin-induced ECG changes, dyslipidaemia, and elevation of CK, CK-MB, LDH, AST, MDA and increased GSH level. Methyl gallate reversed the doxorubicin-induced histopathological changes in the heart. The present study revealed that methyl gallate exerts cardioprotection against doxorubicin-induced cardiotoxicity in female Wistar rats by suppressing oxidative stress. Our study opens the perspective to clinical studies for consideration of methyl gallate as a potential chemoprotectant nutraceutical in the combination chemotherapy with doxorubicin to limit its cardiotoxicity.

The effects of Murraya koenigii leaves are very less studied in streptozotocin-nicotinamide (STZ-NA) induced diabetes rat model, in spite of several studies reported its antidiabetic effects in alloxan and STZ induced diabetes. The present study was undertaken to assess the effects of Murraya koenigii leaves extract on the blood sugar level (BSL) of STZ-NA diabetic rats. Experimental diabetes was induced by STZ injection intraperitoneally (i. p) after 30 min of NA injection i. p in all groups apart from normal control group. Group I (normal control) and Group II (diabetic control) rats received distilled water. Group III rats treated Metformin, Group IV and Group V rats treated Murraya koenigii aqueous extract and Murraya koenigii methanolic extract respectively. BSL and body weights of rats were measured at each week of the period of 28 days. Our results indicate that oral administration of Murraya koenigii reduces BSL significantly compared with the diabetic group. No weight loss was observed in all groups. The findings of the present study suggest that Murraya koenigii is proven as anti-diabetic agent in diabetic rats.

The article presents experimental data on the effect of nickel citrate obtained using nanotechnology on the biochemical parameters of cows’ blood. The animals were divided into 3 groups. Group I was the control one. The animals of the II and III experimental groups received a feed additive of nickel citrate in the amount of 0.1 and 0.3 mg/kg of dry matter of the diet daily during the ninth month of lactation and the first two months after calving. It was found that the addition of both doses of nickel citrate to the transition cows diet contributed to positive changes in some biochemical parameters. A decrease in the content of lipid hydroperoxides, TBA-active products, as well as phenolic compounds was revealed. It should be noted that supplementation cows with nickel citrate in the first month after calving led to a significant increase in the content of lipid hydroperoxides by 15.1% in the third experimental group (P<0.01) against decrease in the level of TBARS by 14.8% compared with the control group (P<0.05). Feeding cows of nickel citrate in the amount of 0.1 mg/kg of dry matter stimulated the binding of free phenols and increased the concentration of their conjugated compounds, particularly phenolglucuronides, in the blood of animals of experimental group II by 20.2% (P<0.05). Instead, the use of nickel citrate in the amount of 0.3 mg/kg of dry matter contributed to a more pronounced activation of detoxification function with increasing concentrations of phenolsulfates and phenolglucuronides in the blood of animals of experimental group III compared with animals of control group by 23.1 and 21.2% (P<0.05).

AbstractObjectives:To determine the effect of royal jelly (RJ) on the oxidant-antioxidant balance in rats with N-methyl-N-nitrosourea (MNU) induced breast cancer and to compare this with the chemotherapeutic agent paclitaxel.Material and methods:Fifty-six female Sprague Dawley rats were divided into five groups. Except control group (n=8, Group I) others received MNU (50 mg/kg, a single dose, i.p.) to develop breast cancer: Group II (n=8) untreated, Group III (n=7) treated with paclitaxel (15 mg/kg/week, 3 times, i.p.), Group IV (n=7) with RJ (by oral gavage, 100 mg/kg/day, for 30 days), and Group V (n=7), with paclitaxel+RJ. At the end of 30 days, histopathological and biochemical parameters were evaluated in breast tissues.Results:Levels of protein carbonyl (PC) and 8-hydroxy-deoxyguanosine (8-OHdG) were higher in Group V than in Group II while malondialdehyde (MDA) levels were lower in groups IV and V compared to Group II (p<0.05). Levels of catalase (CAT) in Group V and glutathione (GSH) in Group III were higher than Group II (p<0.05). Glutathione peroxidase (GPx) and superoxide dismutase (SOD) levels did not significantly different. Decreasing effect of RJ on CA15-3 levels was relevant to histopathological results.Conclusion:Although RJ (with or without paclitaxel) had increasing effect of antioxidant status it was insufficient to reduce oxidative stress in breast cancer.

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.

The study involved 130 patients aged 18-35 years: 70 patients with endometrial polyps (group I), 30 patients with micropolyps (group II) and 30 patients of the control group (group III). Results. According to the anamnesis of women in the I group were significantly more frequent diseases of the cervix, which corrected physical surgery methods, in particular cryodestruction. In group II, the representatives of these indicators were similar to healthy. Normal colposcopic picture met significantly less frequently in patients and I, and II group. The differences in the incidence of HPV high oncogenic risk in all groups were not statistically significant. Conclusion. Destructive methods used in the detection of any changes in the cervix are often overly aggressive, form scars and contributing to inflamaciones process. In the chain of events leading to the formation of PE, cervical pathology and its correction can take the basic place. Key words: endometrial polyp, micropolyps, chronic endometritis, uterine cervix, colposcopy.

The present study was conducted to investigate the efficacy of Ovsynch and Ovsynch plus protocol in postpartum (day 60) Sahiwal cows (n=18). Animals were randomly divided into three equal groups, viz., Ovsynch group Ovsynch plus group and Control group. Animals of group I (n = 6) were treated with traditional Ovsynch protocol. The animals (n = 6) of group II were treated with Ovsynch plus protocol which consisted of an initial intramuscular injection of eCG (Folligon) @ 250 IU on day 60 postpartum followed 3 days later by GPG (Ovsynch) protocol. In group-III Control, no treatment was given to animals (n = 6). Treated animals were inseminated at a fixed time between 14 and 20 hrs after second GnRH injection, irrespective of estrus detection. Blood samples were collected from each animal on days 50 and 60 postpartum to determine the status of cyclicity in animals based on serum concentrations of progesterone (P4). A third blood sample was collected on the day of prostaglandin treatment to determine the response of first GnRH injection. Four animals each were cyclic, and two were acyclic in both treatment groups. Four animals each responded to first GnRH treatment in both treatment groups. Similarly, two animals each got conceived giving conception rate of 50% (2/4) in each treatment. In the control group, one out of 6 animals got conceived yielding 16.66 % conception rate (1/6) during the study period. It may be thus concluded that Ovsynch and Ovsynch plus protocol may be used during the early postpartum period to improve the reproductive efficiency in postpartum Sahiwal cows.
