The study included 1880 necropsies and 8,217 biopsies and surgical pieces seen at the Pathology Department of the Hospital Infantil de México from 1968 to 1977. Among necropsies, two cases (0.10%) of cholecystitis and/or cholecystolithiasis were found and among surgical pieces there were seven (0.08%). Seven cases were females and two males. The symptoms most frequently found were: abdominal pain, jaundice, vomiting and leukocytosis. Morphologically, there were three cases of chronic cholecystitis with cholecystolithiasis, two cases of acute cholecystitis without calculi, two cases of chronic cholecystitis without calculi, one case of acute and chronic cholecystitis without calculi and another one cholecystolithiasis without inflammatory manifestations of the gallbladder. As etiological or predisposing factors we found: obesity, infections, parasitosis, hematologic disturbances, dilatation of the choledochus and one case with diaphragm of the 4th portion of the duodenum.

Four cases of gastric perforation are studied in three male newborns and in a 14-year-old female out of 1949 autopsies performed from 1969 to 1978 at the Pathology Department of Hospital Infantil de México. All four cases showed clinical signs of respiratory failure and anatomical pulmonary lesions; this last feature led in all cases to hypoxia. Based on these data and on the opinion of several authors, hypoxia is believed to be the most important datum in the pathogenesis of gastric perforation in childhood.

A batch of 45 male Wistar rats, weighing 180 to 325 grams, were used in the experiment. Partial hepatectomy was practiced to them and liver biopsies taken at different periods of times: 0 (control) 4, 8, 12, 24, 36, 48, and 72 hours and 45 days. The biopsies were examined at the electron microscope. During liver regeneration, a sequence of morphological changes was detected, having started with an important decrease of cytoplasmic particles, increase of lipids and laminar bodies like myelin. After 24 hours, preparatory changes for cellular regeneration were observed prior to full regeneration which was reached later.
