Objective: To determine the difference in spermatogonium cells, leydig cells and sertoli cells count in white rats testicle (wistar strains) obtained with the combination of cisplatin and vitamin E compared with that only received cisplatin. Material & Methods: There were 4 random groups out of a total of twenty four winstar strain rats (n=6). The control group (I) injected normal saline 0.9% intraperitoneally (i.p.) as the placebo on the 3rd week. Group (II) given cisplatin (5 mg/kgbw) injection i.p. on 3rd week, Group (III) given cisplatin injection 5 mg/kgbw i.p. on 3rd week + vitamin E 50 mg/kgbw by gavage for 7 weeks and group (IV) cisplatin injection 5mg/kgbw i.p. on 3rd week + vitamin E 200 mg/kgbw by gavage for 7 weeks. Vitamin E was given 3 weeks before up to 4 weeks after cisplatin injection (total 7 weeks). Observations by calculating the average number of spermatogonia, sertoli and leydig cells on a cross-sectional section of the seminiferous tubule with Haematoxylin-Eosin staining using a 400x light magnification microscope. Results: Cisplatin decreases spermatogonia, sertoli, and leydig cells significantly against control. Vitamin E 200 mg/kgbw significantly increased the number of spermatogonium, sertoli, and leydig cells (p<0.05) compared to group in combination with vitamin E 50 mg/kg bw and cisplatin or cisplatin only group. Only leydig cells count was significantly increased in the combination group of vitamin E 50 mg/kgbw  and cisplatin compared to the cisplatin group. Conclusion: Vitamin E 200 mg/kgbw provides a protective effect against decreased spermatogonia, sertoli and leydig cells due to cisplatin 5 mg/kgbw exposure which its protectivity depends on the given dose.

Quantitative Ultrastructure

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.

Acupuncture has been shown to be effective in experimental and clinical acute pain settings. This study aims to evaluate the effect of preoperative electroacupuncture (EA) on intraoperative and postoperative analgesic (alfentanil and morphine) requirement in patients scheduled for gynaecologic lower abdominal surgery. Ninety patients were randomly assigned to one of three groups: Group I (control group) –received placebo EA for 45 minutes before induction of general anaesthesia (GA); Group II –preoperative EA instituted 45 minutes before induction of GA; Group III – 45 minutes of postoperative EA. The Bispectral Index monitor was used intraoperatively to monitor the hypnotic effect of anaesthetic drugs, and alfentanil was titrated to maintain the blood pressure and pulse rate within ±15% of basal values. Postoperative pain was managed by intravenous morphine via a patient-controlled analgesia (PCA) device. Patients in Group II (0.44 ± 0.15μg/kg/min) received less alfentanil than those in Group III (0.58 ± 0.22μg/kg/min) (p=0.024), but not significantly less than those in Group I (0.51 ± 0.21μg/kg/min) (p=0.472). Postoperative morphine consumption was numerically lower in Group II compared with the other groups; however, the difference was statistically significant only during the period of 6–12 hours between Group II [0.03 (0.05) mg/kg] and Group I [0.10 (0.11) mg/kg] (p=0.015), and Group II and Group III [0.08 (0.10) mg/kg] (p=0.010). The 24-hour cumulative morphine consumption for Group II (0.52 ± 0.19mg/kg) was less than that for either Group I (0.68 ± 0.38mg/kg) or Group III (0.58 ± 0.27mg/kg), but the difference did not reach significance. In conclusion, preoperative EA leads to a reduced intraoperative alfentanil consumption, though this effect may not be specific, and has a morphine sparing effect during the early postoperative period.

The study was conducted to determine the effects of vitamin E on reproductive performance in mice treated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The 75 female and 40 male mice were randomly assigned into five groups. The levels of both TCDD and vitamin E given by gavage were 0 and 0 (Control group), 100 and 0 (experimental group I), 100 and 20 (experimental group II), 100 and 100 (experimental group III), and 100 ng/kg/day and 500 mg/kg/day (experimental group IV), respectively. Males and females were mixed to mate at the ratio of 1:2 after 4-week experiment. The gavage treatments were continued until the end of gestation in female mice after mating. The results showed that the litter number, survival rate, and body weight at birth of offspring in experimental group I had significantly decreased, and the females’ pregnancy rate and pup sex ratio in experimental group I had the decreasing tendencies when compared with the control group. The litter number in experimental group III, survival rate in experimental group II and III, body weight at birth in experimental group III and IV exhibited significant increase compared with experimental group I. The female pregnancy rate in both experimental group III and IV recovered to 100%, but there were no significant differences when compared with experimental group I. The pups’ sex ratio had a gradually increasing tendency with increase of vitamin E level, but there was no significant difference among experimental group I–IV. The results suggest that TCDD could induce reproductive toxicity in mice, whereas vitamin E alleviated adverse effects on reproductive performance in mice caused by TCDD.

Male reproductive ability ability has a linear correlation with libido and testosterone. Both are associated with various things main food consumption such as protein, vitamins and minerals. Aphrodisiac  is an ingredient or drug that arouses sexual arousal or libido. Pumpkin is an example of food from plants with the highest content of zinc. This study was to determine whether there is a difference between the content of zinc on the peel, flesh and pumpkin seeds against sexual activity of mice. The experimental animals used were 24 male, group I mice as control group, Group II was grouped with pumpkin peel extract, Group III was grouped with extract of pumpkin flesh, Group IV was grouped with extract of pumpkin seeds. The dose used is 2gr / kg BB and volume of 0.2 ml is given for 35 days. Sexual Activity is observed every day  by the position of male mice riding females. Based on Anova One Way test results showed there are differences in sexual activity  mice males in each group (ρ 0.000). The difference of the result of the number of mounts indicated that the giving of yellow pumpkin extract had an effect on the increase of mating behavior of male mice. The group treated with the extract of pumpkin flesh showed the highest number of mice mounts (mean = 24,1667.Further research is needed to get a clearer picture of the composition of the pumpkin nutrients that indirectly affect fertility in men.

AbstractThe aim of this study was to evaluate and compare the sealing ability to obturate oval canals with three thermoplasticizedguttaperchaobturation techniques taking lateral condensation technique as the control. Ninety-five freshly extracted teeth were decoronated at 2mm coronal to CEJ. Biomechanical preparation was done using step back technique. The teeth were divided into three experimental groups of 30 teeth each and one control group of 5 teeth. The group I (control group) was obturated with lateral condensation technique, group II obturated with injectable thermoplasticizedguttapercha technique, group III obturated with thermoplasticizedguttapercha with downpack and backfill technique andgroup IV obturated with core carrier thermoplasticizedguttapercha technique. The sealability of each technique was assessed by a dye penetration method. The roots were given two full layers of nail polish varnish except apical 2mm. Specimens were then immersed in India ink for 48 hours. Robertson’s technique was used to clear the specimens. The linear dye penetration was measured from anatomic apex to the deepest extent of dye penetration in a coronal direction using triocular stereomicroscope at 10 × magnification. The mean dye leakage of group I was 2.6700mm;group II 0.1713mm;group III 3.3977mm; group IV 2.3210mm. When the means of all the four groups were compared using Kruskal Wallis test the difference was found to be very highly significant with the value<.001**, meaning there by that group II is significantly better than the other three groups as far as sealing ability is concerned.

SummaryBackground: The production of erythrocytes is regulated by the hormone erythropoietin (EPO), which maintains the blood haemoglobin (Hb) levels constant under normal conditions. Human EPO is a glycoprotein hormone and its synthesis is controlled by the hypoxia-inducible transcription factor. The aim of this study was to establish EPO and Hb levels in patients with chronic kidney disease (CKD), as well as in control subjects, and to investigate the relationship between these parameters.Methods: This cross-sectional, observational study included 356 subjects with CKD divided into 4 subgroups according to their glomerular filtration rate (GFR). The control group consisted of 206 age and sex matched healthy subjects with GFR rate ≥90 mL/min/1.73 m2. EPO, Hb and serum creatinine levels were determined by using immunochemical and spectrophotometric methods. GFR was determined using the MDRD formula.Results: The CKD patients had significantly lower levels of haemoglobin (p<0.0005) and hematocrit (p<0.0005) compared to control group. Our results showed that Hb levels decreased, whereas serum creatinine increased with the increasing renal failure. The CKD patients in all four groups had significantly lower (p<0.0005) Hb levels, and significantly higher (p<0.0005) creatinine levels compared to the control group. The median EPO in group I and II were significantly higher (p=0.002; p=0.018), while median EPO in group III and IV were significantly lower (p=0.03; p=0.011) compared to the control group.Conclusions: In patients with CKD, GFR positively correlated with Hb and EPO, while the correlation between GFR and serum creatinine was negative.

BACKGROUND: The administration of doxorubicin can increase the production of reactive oxygen species (ROS) and disrupt the balance of antioxidant defenses triggered a cell damage including liver cells and renal cells. Antioxidant from medicinal plants have play role in protecting the cells against ROS. Beetroot tuber contains various phytochemical compound that has an antioxidant property. AIM: The purpose of the study was to determine the protective effect of beetroot ethanol extract on concurrent use of doxorubicin for 15 days by measuring blood levels of aspartate aminotransferase, alanine aminotransferase, Creatinine, blood urea nitrogen and histopathological changes. MATERIALS AND METHODS: Twenty-five male white rats as weighing 180–200 g were divided into five treatment groups. Group I was the normal control group, Group II was a negative control group that only injected doxorubicin with a cumulative dose of 15 mg/kg body weight (BW) for 15 days. Group III-V was the test group given beetroot extract (BE) at doses of 100, 200 and 400 mg, respectively, for 15 days with doxorubicin. RESULTS: The group treated with BE at a dose of 200 mg/kg BW could improve serum levels of liver enzymes compared with negative controls (p < 0.05). The group treated with BE at a dose of 100 mg/kg BW also showed an improved effect on creatinine and BUN levels of rats compared to negative controls (p < 0.05). All parameters showed that the protective activity of beetroot ethanol extract was dependent on increasing the dose. CONCLUSION: This research proves that the compound contained in beetroot ethanol extract has protective activity in liver and kidney of rats induced by doxorubicin.

Introduction: Taking into account the patho-immune mechanisms of formation of inflammatory process in periodontium, there is a necessity for in-depth study of the pathogenesis of periodontal diseases from the position of changes in the reactivity of the organism. The aim: Carrying out a comparative estimation of phagocytic activity of leukocytes of animals with inflammation in periodontium with altered reactivity. Materials and methods: Experiments were performed on 30 white rats: Group I - 10 white rats with hypoergic reaction; Group ІІ - 10 white rats with hyperergic reaction; Group III - 10 white rats with normergic reaction - control group. Slaughter and blood sampling under thiopental anesthesia was performed 7 days after the beginning of the experiment. The percentage of phagocytic leukocytes - phagocytic index, phagocytic number were determined and the index of phagocytic activity was calculated. Results: The phagocytic index (Fi,%) decreased by 2,09 times (p <0,05) at hypoergic, it increased by 1,37 times (p <0,05) at hyperergic; the index of phagocytic activity (IFA) decreased by 1.96 times at hypoergic (p <0.05); growth was 1.94 times (p <0.05) in the hyperergic group of animals. In both experimental groups, the phagocyte number (Fu) increased by 6.25% and 41.7%, with hypoergic and hyperergic, respectively. Conclusions: Different directions of changes of the phagocytic activity were observed: increase of these parameters at hyperergic and decrease at hypoergic. An increase in phagocyte number was likely to indicate some autonomy of the process of phagocytosis and independence from the reactivity of the organism.
