Diabetes Mellitus (DM) is a condition of hyperglycemia due to defects of insulin secretion and/or insulin action. Toxic metals such as lead, nickel, cadmium, arsenic and mercury have been identified which accumulate in various biological samples from T2D (type 2 diabetes) patients through environmental pollution and food chain. Present study will elucidate the toxicological effects of mercury (II) chloride in the pancreatic islets and liver tissues of rat which leads to dysfunction and degeneration of pancreatic islets and liver. Photomicrograph of histology of treated pancreas exhibited the disruption of islets, disorientation of cells and disruption of connective tissue septa. In mercury (II) chloride treated group pancreatic cells were found to be pyknotic and cellular death was confirmed by membrane rupture and necrosis. Alteration of blood glucose levels were observed by glucose tolerance test. The liver sections of rats treated with mercury (II) chloride showed modification in the structure of this organ. Treated liver showed lower periodic acid/Schiff response. In this study, changes in the architecture of pancreatic islets as well as liver may be the reason behind diabetes.

Background:Candida chorioamnionitis is rarely encountered, even though vulvovaginal candidiasis incidence is about 15%. Interestingly, it has characteristic gross and histological findings on the umbilical cord that are not to be missed. Case Report: We report two cases of Candida chorioamnionitis with presence of multiple yellowish and red spots of the surface of the umbilical cord. Microscopically, these consist of microabscesses with evidence of fungal yeasts and pseudohyphae. The yeasts and pseudohyphae were highlighted by periodic acid– Schiff and Grocott methenamine silver histochemical stains. Both cases were associated with a history of gestational diabetes mellitus. Discussion: Peripheral funisitis is a characteristic feature of Candida chorioamnionitis. It is associated with high risk of adverse perinatal and neonatal outcomes, such as preterm delivery, stillbirth and neonatal death. We recommend careful examination of the umbilical cord of mothers with gestational diabetes mellitus.

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycaemia. Functional food, such as kombucha tea, is widely used as complementary treatment for type 2 diabetes mellitus.  Kombucha tea is made through fermentation process of green or black tea using a microbial kombucha consortium (Acetobacter xylinum and several types of yeast). The aim of this study was to evaluate the effect of fermentation time of kombucha tea on its hypoglycaemic activity in rats. The green tea (Camellia sinensis) was fermented with kombucha consortium for 8, 14, and 21 days. Evaluation of hypoglycaemic activity was conducted using glucose tolerance test method. First, fasting blood glucose levels in rats were measured after 16 hours fasting.  Hyperglycaemic condition was induced by administering glucose 2 g/0.2 kg body weight. Blood glucose levels were measured again after 30 minutes. Subsequently, 5.5 ml of kombucha tea in various fermentation time was orally administered. Blood glucose levels were measured at 30, 60, 90, 120, 150 and 180 minutes after kombucha tea administration. The results revealed the average reduction of blood glucose were 18.16%, 33.64%, and 19.88% by kombucha tea fermented for 8, 14, and 21 days, respectively. In conclusion, kombucha tea fermented for 14 days is potential to be developed as a hypoglycaemic agent. Keywords: fermentation time, glucose level, hypoglycaemia, kombucha tea

Background: Diabetes mellitus (DM) is a dangerous disease with prevalence in Indonesia, including South Sulawesi, until now it has reached 3.4% of the total population. Prediabetes is an early condition for diabetes where blood glucose levels are above normal levels. One of the factors that are most closely related to the incidence of prediabetes is obesity which is also a problem currently faced at the age of children and adolescents. One way to detect a disturbance in glucose metabolism is the Oral Glucose Tolerance Test (TTGO).Objective: This study aims to determine the incidence of prediabetes in obese students. Methods: The study design was analytical descriptive, analyzing the test variables of OGTT as a prediabetes screening in the obese. The population was all active students of Megarezky University who were obese obtained by purposive sampling technique. Results: Based on the research result of 40 respondents, after the measured levels of GDP and two-hour glucose levels after oral glucose administration (postprandial), obtained a mean grade of respondents OGTT was 120,45 mg/dl and 8 (20%) of whom had an abnormal OGTT level ( 140-199 mg/dl). Conclusion: It reveals that the eight respondents experienced impaired glucose tolerance (IGT) and prediabetes. Obese people should begin to keep a balance between intake and energy expended to avoid Diabetes Mellitus.

Background: Modern desk-bound lifestyle and unhealthy dietary changes have brought a rise in the prevalence of obesity and gestational diabetes mellitus (GDM). It is associated with severe hazards to the mother and the baby. It is mandatory that early diagnosis ensues and timely and congruous management is undertaken.Methods: In this observational study, 1250 women were included. A standardized questionnaire was formed and their details were noted. Tests for glucose levels, complete blood picture, urine examination were performed. An oral glucose tolerance test was performed on all the patients. Neonatal outcomes in terms of birth weight and the presence of complications were noted.Results: A total 201 (16.1%) of all women were having gestational diabetes mellitus (GDM). Most mothers were in the 25-30 age group. The majority of the women had a BMI between 26-30. 21.9% of babies were having weight >3.5 kgs. 11.4% of babies were <2.5 kgs. Out of 201 neonates, 90 babies were having complications. Major complications in neonates were macrosomia and respiratory distress. Therefore, early diagnosis, glycemic control, and timely and congruous management are advantageous to both mother and baby.Conclusions: GDM complicating the pregnancy results in a higher prevalence of complications in the mother and the neonate. Therefore, appropriate control of the sugar level in mothers is necessary and it decreases the morbidity and mortality rates in the babies as well as the mothers.

Abstract: With the hypothesis that blocking chemokine signaling can ameliorate acute laminitis, the aim was to evaluate the therapeutic effect of intravenous DF1681B, a selective antagonist for CXCR1 and CXCR2 (chemokine receptors), in an oligofructose equine laminitis model. To twelve mixed breed clinically healthy hoses with no previous history of hoof-related lameness was administered oligofructose (10g/kg given by nasogastric tube) and divided into two groups: treated (intravenous DF1681B at 30mg/kg 6, 12, 18, and 24h after oligofructose) and non-treated groups. Laminar biopsies were performed before and 12, 36, and 72h after administering oligofructose. Samples were stained with periodic acid-Schiff (PAS) and scored from 0 to 6 according to epidermal cell and basal membrane changes. The IL-1β, IL-6, and CXCL1 RNA expressions were determined by RT-PCR. Parametric and non-parametric tests were used to compare times within each group (P<0.05). The PAS grades and IL-1β and IL-6 RNA expression increased in the non-treated group, but remained constant in the treated horses. In conclusion, DF1681B therapy reduced laminar inflammation and epidermal deterioration in treated horses. CXCR1/2 blockage should be considered therapeutically for equine acute laminitis.

Pituitary glands from 141 feline autopsy cases were reviewed histologically. Adenoma and hyperplasia were the most common lesions at 13 cases each. Pituitary adenoma was more likely than hyperplasia to be associated with clinical evidence of endocrinopathy or an intracranial mass ( P < .001). A histochemical and immunohistochemical panel was applied to 44 autopsy- or hypophysectomy-derived pituitary adenomas in 43 cats from 2 diagnostic laboratories. Adenomas were differentiated from hyperplasia by the presence of disrupted reticulin fibers. One cat had a double (somatotroph and melanotroph) adenoma. Twenty somatotroph adenomas consisted of periodic acid-Schiff (PAS)-negative acidophils that expressed growth hormone; 16/20 had hypersomatotropism; 17/20 had diabetes mellitus. Eleven melanotroph adenomas consisted of PAS-positive basophils or chromophobes that expressed melanocyte-stimulating and adrenocorticotrophic hormones; 5/11 had hypercortisolism; 6/11 had diabetes mellitus. Eleven gonadotroph adenomas consisted of PAS-negative chromophobes that expressed follicle-stimulating and/or luteinizing hormones. Two thyrotroph adenomas consisted of PAS-negative basophils or chromophobes that expressed thyroid-stimulating hormone. Pituitary-dependent disease was not recognized in cats with gonadotroph or thyrotroph adenomas. The Ki-67 proliferation index in hypophysectomy specimens was lower in somatotroph than in melanotroph adenomas. Fourteen cats with hypophysectomy-treated somatotroph or melanotroph adenoma had an 899-day median survival time versus 173 days in 17 nonsurgical cases. After adjusting for age, adenoma size and type, hypophysectomized cats had an overall better survival time than nonsurgical cases ( P = .029). The study results underscore the value of hypophysectomy and trophic hormone immunohistochemistry in the treatment and classification of feline pituitary adenomas.

The distinguishing clinical features of Cushing's syndrome in the cat include very friable skin, a high incidence of diabetes mellitus, and the general absence of steroid hepatopathy. This case report describes a nine-year-old, spayed female domestic shorthair with triamcinolone-induced Cushing's syndrome. Unique to this cat were markedly elevated liver enzymes which prompted an expanded clinical evaluation. An ultrasonographic-guided liver biopsy demonstrated diffuse hepatocellular vacuolation that stained periodic acid-Schiff (PAS) positive and was removed subsequently with diastase application, indicating glycogen accumulation. These findings are compatible with the rarely seen syndrome of steroid hepatopathy in the cat.

The morphology of canine platelets (changes in size, shape, staining characteristics, degree of activation and clump formation, distribution of granules, appearance of vacuoles on Giemsa-stained smears) was investigated in 20 healthy control and 181 diseased dogs. In the group of the sick dogs 84 animals suffered from disorders affecting directly the haematological parameters or the haematopoietic organs such as bleeding, thymic haemorrhage, haemolytic disorders, lymphoma, immune-mediated thrombocytopenia, and other 97 dogs were affected by other diseases (hepatopathy, nephropathy, hepatic, splenic or intestinal neoplasm, skin diseases, diabetes mellitus, Cushing'ssyndrome, sepsis). The alterations found in platelet morphology were not specific for any disorder. The most common platelet abnormalities were polychromasia and the presence of giant platelets. These changes occurred in a high number in disorders accompanied by bleeding or haemolysis. Anisocytosis was the most frequent finding in hepatic, splenic or intestinal neoplasms and in certain endocrinopathies. Microcytosis was observed in immune-mediated thrombocytopenia, hepatic neoplasms and endocrine disorders. Extreme platelet activation was common in haemolysis, hepatopathies, neoplastic diseases and sepsis. Vacuolisation was present in thymic haemorrhage, pancreatitis, diabetes mellitus and Cushing's syndrome. A new morphologic phenomenon, i.e. a ring-like formation of granules, was described in the cytoplasm of the platelets both in healthy and diseased animals. In addition, two forms of pathologic granulation were also described for the first time in Giemsa-stained blood smears: the pseudonuclear and the spot-like formation of granules, which were observed especially in disorders affecting the blood cells. The granulation and morphological characteristics of platelets on smears stained by periodic acid-Schiff reaction (PAS) were also studied. Three localisations of granulation were observed, such as peripheral, eccentric and diffuse. The ratio of PAS-positive and -negative platelets was evaluated in several diseases. Our findings support the diagnostic value of platelet evaluation by light microscopy and help clinicians/clinical pathologists to understand why morphologic changes of thrombocytes might be expected in several diseases.

This study investigated the protective effect of vitamin D against carbon tetrachloride (CCl4)-induced nephrotoxicity in rats. Adult male Wistar albino rats were divided into four groups ((A) control; (B) 10-week exposure to CCl4; (C) 10-week exposure to CCl4 + vitamin D treatment; and (D) 10-week exposure to CCl4 + 12 weeks of vitamin D treatment). The CCl4 dose (1.5 ml kg−1) was injected subcutaneously twice a week, while the 0.5 mg kg−1 dose of vitamin D was administered intraperitoneally every day, as appropriate for each group. Whole animal and kidney weights as well as serum urea, creatinine, and glucose levels were measured. Kidney tissue sections were stained with hematoxylin–eosin, Masson’s trichrome, and periodic acid–Schiff. Tubular and glomerular degeneration were detected in the kidney tissues of CCl4-treated rats, together with dilatation and vacuolization within the tubules and hemorrhage in the intertubular region. In the kidney glomeruli; congestion, atrophy, and adhesion to parietal layer were observed. Tissue disorganization and aggregation of Bowman’s capsules were noted. Mononuclear cell infiltration was observed between the glomeruli and the tubules. In contrast, the kidney sections and functional parameters of vitamin D-treated rats were similar to the controls, suggesting that vitamin D treatment is able to reduce renal damage.
