In ams-shock of rats the weight of the small bowel contents of an animal 310 g of weight increases from 2.5 g to 13.0 g. The fluid loss into the bowel lumen amounts to 10.5 g and exceeds the plasma volume of 9.6 g. Drainage into the large bowel is not taken into consideration. After treatment of the ams-shock with gelatine infusion the weight of the small bowel wall increases significantly for a limited period of time to 3.2 g% body weight compared to normal controls with 2.3 g% body weight. After at least 24 hours the necrotic epithelium of the small bowel is fully recovered. Following ams-shock it is possible by means of gelatine infusion to improve the time and rate of survival significantly and to give support to the theory of volume loss.

Safe access to laparoscopic cholecystectomy in patients with previous periumbilical incsions: new approach to avoid entry related bowel injury.
Langenbecks Arch Surg
January 2025
Alexandria Main University Hospital, Alexandria, Egypt.
Background: Patients with prior abdominal surgeries are at higher risk of intra-peritoneal adhesions near the trocar entry site, increasing the likelihood of organ injury during laparoscopic cholecystectomy (LC). This study evaluates a novel technique where the epigastric trocar is inserted first, after creating pneumoperitoneum, to allow safe dissection of adhesions under direct vision before placing the umbilical trocar.
Methods: This prospective study included 244 patients with symptomatic uncomplicated gallstone disease and a history of previous abdominal surgeries extending to the umbilicus.
First-line biologics as a treatment for ulcerative colitis: a multicenter randomized control study.

Department of Gastroenterology and Hepatology, Kyorin University School of Medicine, Mitaka, Japan.
Background: Despite the availability of several biologics for ulcerative colitis (UC), there remains a critical need to identify first-line treatment biologics. The superiority of infliximab (IFX) over vedolizumab (VED) and ustekinumab (UST) was evaluated as initial UC treatments in patients with biologic-naïve UC.
Methods: This multicenter, randomized control trial was conducted across 20 Japanese medical institutions.

Intoxication of sheep and cattle by recently occurred in Uruguay and Argentina in association with severe drought. Although the disease was experimentally reproduced in sheep in the 1970s, there is limited information on clinical and pathologic findings of sheep experimentally intoxicated by this beetle. Here, we described the clinical, gross, and microscopic findings in 3 sheep orally dosed with (treatment group, TG) and in 2 control sheep (control group, CG) dosed with distilled water.
