BACKGROUND: Cryptorchidism is associated with the risk of infertility and can be a symptom of congenital sexual maldevelopment. AIM: To assess the functional status of the pituitary gland and sexual glands in boys aged 16 months with bilateral inguinal cryptorchidism and to reveal the congenital sexual maldevelopment during minipuberty. METHODS: Twenty-one boys aged 16 months (the minipuberty period) with isolated bilateral inguinal cryptorchidism and 40 healthy boys aged 23 months (the control group) were examined. The gonadal status was assessed and serum levels of sex hormones were measured. Molecular genetic testing was performed if there were indications for it. RESULTS: The results of hormone analysis were used to divide the patients into three groups: group 1 patients with normal serum levels of gonadotropin and sex hormones; group 2 patients with elevated gonadotropin level and low levels of anti-Mllerian hormone (AMH) and inhibin B, and group 3 patients with zero gonadotropin and testosterone levels and low levels of AMH and inhibin B. Group 1 patients had no functional disturbances in the pituitarygonadal system. Failure of Sertoli cells associated with a high risk of infertility was detected in group 2 patients. Group 3 patients were diagnosed with hypogonadotropic hypogonadism verified by molecular genetic tests. CONCLUSION: Hormonal testing of patients with bilateral inguinal cryptorchidism during minipuberty makes it possible to early detect the congenital sexual maldevelopment.

Background The aim of this study was to evaluate the postoperative morphine-sparing effects and reduction in pain and secondary mechanical hyperalgesia after preincisional or postincisional epidural administration of a local anesthetic and an opioid compared with a sham epidural control. Methods Patients undergoing major gynecologic surgery by laparotomy were randomly assigned to three groups and studied in a double-blinded manner. Group 1 received epidural lidocaine and fentanyl before incision and epidural saline 40 min after incision. Group 2 received epidural saline before incision and epidural lidocaine and fentanyl 40 min after incision. Group 3 received a sham epidural control (with saline injected into a catheter taped to the back) before and 40 min after incision. All patients underwent surgery with general anesthesia. Results One hundred forty-one patients completed the study (group 1, n = 45; group 2, n = 49; group 3, n = 47). Cumulative patient-controlled analgesia morphine consumption at 48 h was significantly lower (P = 0.04) in group 1 (89.8 +/- 43.3 mg) than group 3 (112.5 +/- 71.5 mg) but not group 2 (95.4 +/- 60.2 mg), although the hourly rate of morphine consumption between 24 and 48 h after surgery was significantly lower (P &lt; 0.0009) in group 1 (1.25 +/- 0.02 mg/h) than group 2 (1.41 +/- 0.02 mg/h). Twenty-four hours after surgery, the visual analog scale pain score on movement was significantly less intense (P = 0.005) in group 1 (4.9 +/- 2.2 cm) than group 3 (6.0 +/- 2.6 cm) but not group 2 (5.3 +/- 2.5 cm), and the von Frey pain threshold near the wound was significantly higher (P = 0.03) in group 1 (6.4 +/- 0.6 log mg) than in group 3 (6.1 +/- 0.8 log mg) but not group 2 (6.2 +/- 0.7 log mg). Conclusions Preincisional administration of epidural lidocaine and fentanyl was associated with a significantly lower rate of morphine use, lower cumulative morphine consumption, and reduced hyperalgesia compared with a sham epidural condition. These results highlight the importance of including a standard treatment control group to avoid the problems of interpretation that arise when two-group studies of preemptive analgesia (preincisional vs. postsurgery) fail to find the anticipated effects.

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats.  A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.

A randomized, controlled clinical trial was performed to determine whether individualized dosing by use of Bayesian pharmacokinetic modeling could decrease nephrotoxicity accosted with aminoglycoside therapy. Two hundred forty-three patients receiving aminoglycosides for suspected or proven infection were randomly assigned to one of three groups: usual physician-directed dosing (Group 1), pharmacist-assisted dosing (Group 2), or pharmacist-directed dosing (Group 3). Dosing in Groups 2 and 3 was based on a Bayesian pharmacokinetic dosing program, whereas Group 1 served as the control group. Individualized dosing resulted in higher mean postinfusion (peak) serum aminoglycoside levels, higher ratios of mean peak level to minimum inhibitory concentration (peak/MIC ratios), and a trend toward lower trough serum levels. Milligrams per dose were higher and number of doses per day was lower in the pharmacist-dosed groups. However, the incidence of nephrotoxicity (> or = 100% increase in serum creatinine) was not different among the three groups (16, 27, and 16% in Groups 1, 2, and 3, respectively). Similarly, severity of toxicity was not affected by the dosing intervention. Risk factors for toxicity included duration of therapy, shock, treatment with furosemide, older age, and liver disease. After controlling for these factors, the dosing intervention still had no effect on nephrotoxicity. It was concluded that Bayesian pharmacokinetic dosing did not decrease the risk of nephrotoxicity associated with aminoglycoside therapy.

Background & Aims: ProBNP is a sensitive marker of cardiac dysfunction. We assessed the concentration of circulating NT-proBNP in patients with liver cirrhosis in various stages of the disease and its correlation with markers of cardiac and renal dysfunction and with markers of liver disease severity.Patients and methods: A number of 88 patients with liver cirrhosis were included in the study, divided into 3 groups: group 1 - 18 control patients without ascites; group 2 - 35 non-azotemic patients with ascites; group 3 - 35 patients with hepatorenal syndrome. The cardiac dysfunction was assessed by measuring the NT-proBNP serum levels and the QTc interval. The markers of renal dysfunction were the estimated glomerular filtration rates - formulas involving creatinine and serum cystatin C. The Child-Pugh score was used to assess the liver disease severity.Results: The median NT-proBNP serum levels significantly increased in patients with advanced liver cirrhosis (group 3: 960 fmol/ml and group 2:  660 fmol/ml) as compared to group 1 (435 fmol/ml) (p<0.05). A significant direct correlation was found between the NT-proBNP concentration and the QTc interval (r=0.540, p<0.001). The NT-proBNP levels also correlated with the Child-Pugh score (r=0.501, p<0.01), proving the link between the cardiac dysfunction and the liver disease severity. The cardio-renal interrelation is supported by the relationship between the NT-proBNP concentration and the estimated clearances.Conclusion: The high NT-proBNP levels in patients with advanced cirrhosis indicate the presence of cardiac dysfunction, which has a role in the pathogenesis of the hepatorenal syndrome.Abbreviations: DP: diastolic pressure; GFR: glomerular filtration rate; HRS: hepatorenal syndrome; MAP:mean arterial pressure; NT-proBNP: N-terminal fragment of the prohormone B-type natriuretic peptide; proBNP: prohormone brain natriuretic peptide; SBP: spontaneous bacterial peritonitis; SP: systolic pressure; TIPS: tranjugular intrahepatic portosystemic shunt.

This study was designed to evaluate antischistosomal activity of Nitazoxanide (NTZ) in Schistosoma mansoni-infected mice compared to Praziquantel (PZQ). Fifty four infected mice were recruited into 3 groups, each of 18 mice. Group 1 was infected non-treated control. Group 2 was infected and then treated with PZQ 500 mg for two days, and group 3 was infected and treated with NTZ 100 mg/kg for seven days. Efficacy of drugs was assessed by Parasitological, and scanning electron microscopic studies. PZQ reduced (4.9%, 22.5% and 50.7%) of faecal eggs, (22%, 22.6% and 55.1%) of intestinal eggs, (20.4%, 44.3% and 46.7%) of hepatic egg counts and (27%, 45.1% and 64.9%) of total worm load whereas, NTZ reduced (4.9%, 22.5% and 50.7%),of faecal eggs, (22%, 22.6% and 55.1%) of intestinal eggs ,(20.4%, 44.3% and 46.7%) of hepatic egg counts and (27%, 45.1% and 64.9%) of total worm load at 1, 2 and 4 WPT, respectively. The percentages of dead eggs were more than 80% after PZQ treatment and only 30% after NTZ at 4 WPT. PZQ showed extensive tegumental damages in male and female worms more than NTZ at 2 WPT. Our findings concluded that Nitazoxanide showed weaker antischistosomal activity in animal models than praziquantel.

SummaryObjective: To investigate the effects of various activation methods on freeze–thawed rabbit oocytes developmental potential. Methods: Rabbit oocytes were vitrified by cryoleafs and cryoprotected with ethylene glycol and propanediol. After thawing, the oocytes were fertilized by intracytoplasmic sperm injection (ICSI). Surviving oocytes after ICSI were divided into five groups at random. Group 1: Oocytes (n = 30) activated 1 h after ICSI by calcium ionomycin (I0634); Group 2: Oocytes (n = 26) activated by strontium chloride an hour after ICSI; Group 3: Oocytes (n = 33) activated by I0634 twice; Group 4: Oocytes (n = 28) were activated by strontium chloride twice; Control Group: Inactivated oocytes (n = 39). Blastocysts derived from each group were transplanted to recipient rabbits. Results: Rates of fertilization, cleavage and blastocyst formation of Group 3 were higher than those of Group 1 and Group 2 (81.8% vs 33.3% vs 53.8%, 54.5% vs 16.7% vs 26.9%, p < 0.05; 15.2% vs 3.3% vs 7.7%, p > 0.05). The rabbit transplanted with embryos derived from Group 3 became pregnant. Embryos derived from double activation could implant into endometrium. Conclusion: Double activation may increase freeze–thawed oocytes developmental potential. After activation, oocytes cleavage velocity may be faster than that of oocytes without activation.

Abstract Background: Premature ovarian failure is among the most important side effects of chemotherapy during reproductive period. Preserving ovarian function is gradually gaining importance during oncologic treatment. The present study aims to investigate the potential of melatonin to protect from cisplatin-induced ovarian toxicity in rats. Twenty nine female rats were divided to three groups: Saline control group (Group 1), cisplatin group (Group 2), and cisplatin+melatonin group (Group 3). While the rats in Groups 2 and 3 were administered 5 mg/kg single dose of cisplatin via intra-peritoneal (IP) route, the rats in Group 3 were started on melatonin (20 mg/kg IP) before cisplatin administration and continued during 3 consecutive days. Ovaries were removed one week after cisplatin administration in all groups. Blood samples were obtained before the rats were decapited. Histological evaluation, follicle count, and classification were performed. TAp63 mRNA expression was evaluated using mRNA extraction and real-time polymerase chain reaction (PCR) method. Serum estradiol (E2) and anti-mullerian hormone (AMH) values were measured with enzyme immune-assay technology. Results: While primordial follicles were seen to decrease in Group 2 as compared to Group 1 (p:0.023), primordial follicle count was observed to be preserved significantly in melatonin group as compared to Group 2 (p:0.047). Moreover, cisplatin-induced histo-pathological morphology was preserved in favor of normal histology in melatonin group. A significant difference was not observed between groups with regard to mean serum AMH and E2 values (p:0.102 and p:0.411, respectively). While TAp63 gene expression significantly increased in Group 2 as compared to control group (p:0.001), we did not detect a statistically significant difference in cisplatin+melatonin group, although gene expression decreased (p:0.34). Conclusion: We conclude that concurrent administration of melatonin and cisplatin may protect from ovarian damage.
