The article presents the comparative analysis of the state of the cervix in women with endometrial polyps and micropolyps. Patients and methods. 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.

Irisin is a new myokine that is suspected to influence metabolic syndrome (MetS). However, there is a great controversy with respect to its level in cases of MetS and its correlation with different metabolic parameters. The present study assesses irisin levels in MetS patients and studies its relationship to metabolic and liver functions to evaluate the possible role of the liver in regulation of this level. Sixty subjects were included in this experiment, who were divided into 3 groups: group I (normal control), group II (MetS patients with normal liver enzymes), and group III (MetS with elevated liver enzymes and fatty liver disease). Serum irisin levels showed significant increases in groups II and III compared with group I, and significant increases in group III compared with group II. Also, irisin levels were positively correlated with body mass index, serum triglycerides, homeostatic model assessment of insulin resistance index (HOMA-IR), and liver enzymes. We concluded that serum irisin levels increased in patients with MetS, especially those with elevated liver enzymes, and had a positive correlation with parameters of lipid metabolism and glucose homeostasis with the possibility of hepatic clearance to irisin.

Introduction: Diabetes melitus (DM) and hypertension are the most frequent causes of kidney function damage. Many different tests are developed to detect reversible functional kidney changes (detection of microalbuminuria and selective urinary enzymes). Objective The aim of our study was to examine tubular kidney function in type 2 DM patients with different proteinuria levels, and to compare these results with healthy people. Method The patients with type 2 DM and creatinine clearance >80 ml/min were included in the study. According to the levels of proteinuria, the patients were classified in three groups: group I - patients with proteinuria <300 mg/24 h, and no microalbuminuria; group II - the patients with proteinuria <300 mg/24 h and microalbuminuria >20 mg/24 h; and group III- the patients with proteinuria >300 mg/24 h. The control group consisted of healthy subjects. Results The study revealed that in type 2 DM patients and normal global kidney function, fractional excretions of sodium, potassium, and phosphates as well as renal phosphate concentrations were not adequately sensitive markers to detect damage in tubular kidney function in DM. There were some changes of urate fractional excretion in these patients: this value was significantly lower in patients with microalbuminuria compared with those with proteinuria >300 mg/24 h, as well as in the control group (p<0.05). Hormone dependent tubular kidney activity, urinary osmolarity, and urea fractional excretion in all patients were within normal ranges. Conclusion It is evident that routine laboratory analyses are not sensitive markers to detect early changes of kidney function in type 2 DM.

It has been shown that guineapigs can be effectively protected against re-infection by the subcutaneous inoculation of embryonated Ascaris eggs (Soulsby, 1957). The purpose of this communication is to report a successful attempt to immunize guineapigs against a lethal oral challenge dose of eggs by the intravenous inoculation of third stage larvae of A. suum.Three groups, each containing nine guineapigs, were infected with Ascaris as follows: Group I was given 10,000 eggs by mouth. Group II Was inoculated intravenously with 2,000 third stage Ascaris larvae which had been obtained from the lungs of other guineapigs on the sixth day of infection. Both groups were challenged at the same time with 250,000 eggs by mouth, along with a control group (Group III) which had no previous infection. The guineapigs in Group I were re-infected after 18 days and those in Group II after 12 days.

Optical coherence tomography angiography (OCTA) is a recently established noninvasive technology for evaluation of the retinal and choroidal vasculature. The literature regarding the findings in macular telangiectasia type 2 (MacTel2) is scarce. We report the OCTA findings associated with a subject with MacTel2 and secondary subretinal neovascularization (SNV). The commercially available Cirrus 5000 with AngioPlex (Zeiss, Jena, Germany) was used, without any subsequent image modification or processing. Subretinal neovascularization was detectable with OCTA at the level of the outer retina and choriocapillaris. Microvascular abnormalities associated with MacTel2 were present mostly in the deep capillary plexus of the retina temporally.

Background: Nephrotoxicity is characterized by raised serum urea and creatinine levels and kidneys being one of the primary organs of drug concentration and excretion are vulnerable to many widely used marketed drugs, including anti-cancer drugs, antibiotics, immunosuppressants, and radio contrast agents, are nephrotoxic. Aim: To determine the nephroprotective effect of ethanolic extract of Carica papaya seeds in Aminoglycoside induced acute nephrotoxicity. Study design: Quasi Experimental study. Methodology: Thirty Sprague Dawley rats were sub divided into 3 groups i.e., I, II and III with 10 rats in each group. Group II and III were administered Aminoglycoside drug; Gentamycin in 80 mg/kg) via intraperitoneal route once daily for 5 consecutive days to induce acute nephrotoxicity. At day 6, nephrotoxicity was confirmed by measuring serum urea and creatinine. Ethanolic extract of Carica papaya seeds (1000 mg/kg) was started once daily through oral route in group III for 5 consecutive days to see the nephroprotective effects of seed extract after causing acute kidney injury. All animals were given standard diet pellets manufactured at NIH. Results: Mean serum urea and creatinine for Group I (Control Group) at day 0 were 24.90 mg/dL ± 1.633 and .750 mg/dL ± .0619 respectively. Mean serum urea and creatinine for Group II (Disease Control Group) was 81.00 mg/dL ± 1.247 and 1.980mg/dL ± .0467 at day 6th. This suggested induction of nephrotoxicity by Gentamycin. Mean serum urea and creatinine for Group III (Ethanolic Extract Treated Group) at 11 day was 72.40mg/dL± .991 and 1.680 mg/dL± .0467 after 5 days treatment with ethanolic extract of Carica papaya seeds. Conclusion: We concluded that ethanolic extract of Carica papaya seeds has significant nephroprotective effects on Aminoglycoside induced acute nephrotoxicity in rats.

Abstract Background The duration of birth is an important factor influencing the survival of piglets and the health of sows. A prolonged parturition is usually treated with oxytocin, even though several undesirable side effects are described. Therefore, the aim of this study was to evaluate the safety and efficacy of Prostaglandin E2 (PGE2) of different concentrations as an intravaginal applied gel in sows. MethodsTwelve sows were randomly allocated to one of four treatment groups: Group I (control group) application of placebo gel; Group II application of 2.0 mg PGE2; Group III application of 1.0 mg PGE2; Group IV application of 0.5 mg PGE2. The gel was administered intravaginal after the birth of the fourth piglet. Total duration of birth (time between first piglet and last placenta), piglet interval and placenta expulsion duration (time between first and last placenta) were recorded, and each piglet was scored for meconium staining and vitality. Furthermore, stillborn piglets were categorized into ante-partum and intra-partum deaths. Results Although no significant differences between the groups were detected, a beneficial tendency in several parameters was observed in group III. The duration of birth was 284 min (average of 14.3 piglets per litter), whereas in all other groups it was more than 400 min (average of 18.0 piglets per litter). The piglet interval was 10.1 min in group II compared to 10.2 min in group III, 16 min in group IV and 21.4 min in group I. In group III the placenta expulsion duration was 119 min in contrast to the other groups with more than 266 min. Severe meconium staining in more than 10% of piglets was observed in group II and IV. Moreover, piglets of group II showed oedematous and haemorrhagic umbilical cords, lethargy and anoxia, and intra-partum deaths were recorded. Conclusion Although the sample size is limited in this study, it is assumed that an application of 1mg PGE2 intra-partum instead of lower or higher dosages has the most beneficial effects on the birth process in sows and on the vitality of piglets. Further investigation is necessary to confirm the positive effect of PGE2 in daily practise.
