Histomorphological evaluation of colon lesions

Background: Both macroscopic and microscopic appearance helps in identification of the colon lesion which supports in the treatment of the patient in a better way. The authors were aimed at the prevalence of various colon lesions site wise distribution of various neoplastic and non-neoplastic lesions of the patients and to compare the distribution according to their age, sex and site.Methods: A retrospective study was designed to study of various intestinal biopsies sent for histopathological examination at Department of Pathology, N.H.L. Municipal Medical College and V.S. Hospital, Ahmedabad, from January 2015 to December 2016 for period of 2 years. The study was based on the histomorphological evaluation of colon lesions received during the study period.Results: A male preponderance was seen in the incidence of tumors irrespective of tumor type and site of tumor and M:F ratio was 1.64:1. In the large intestine, adenocarcinomas were the commonest malignant tumor. 46 cases (62.61%) were reported. The highest occurrence of appendicitis is in the 2nd and 3rd decade.Conclusions: The study revealed that various types of lesions in large intestine along with the age group and gender affected more. Male patients were majorly affected. Morphological identification helped to diagnose the type of lesion for early diagnosis. This study focuses the role of histopathological identification in early diagnosis of the disease so that the survival rates in such cases will be increased

Interaction of Aqueous Extract of Pleurotus pulmonarius (Fr.) Quel-Champ. with Glyburide in Alloxan Induced Diabetic Mice

Mushrooms are low calorie food with very little fat and are highly suitable for obese persons. With no starch and very low sugars, they are the ‘delight of the diabetics’. Combination of herbal drugs (or isolated phytochemicals) is found to be beneficial in certain diseases when given along with conventional drugs. The aim of the present study was to evaluate the effects of aqueous extract of Pleurotus pulmonarius (Lentinaceae) (called as PP-aqu) and its interaction with glyburide in alloxan induced diabetic mice. The diabetic mice treated were with PP-aqu (500 mg/kg, p.o.) alone or combination with glyburide (10 mg/kg, p.o.) for 28 days. Blood samples were collected by orbital sinus puncture using heparinized capillary glass tubes and were analyzed for serum glucose on 0, 7th, 14th, 21st and 28th days. Body weights and mortality were noted during the study period. In oral glucose tolerance test (OGTT), glucose (2.5 g/kg, p.o.) was administered with either vehicle, PP-aqu alone or in combination with glyburide and serum glucose level analyzed at 0, 30, 60 and 120 min after drug administration. Administration of PP-aqu (500 mg/kg) and its combination with glyburide (10 mg/kg) significantly (P < 0.001) decreased serum glucose level in diabetic mice. In OGTT, glyburide or PP-aqu treatment alone or their combination produced significant (P < 0.001) increase in glucose threshold. Thus we suggest that P. pulmonarius showed potent and synergistic antihyperglycemic effect in combination with glyburide
