Following artificial ulceration of the guinea pig bladder epithelium, study by light microscopy showed that mitotic activity occurs within 24 hours in the basal layer of the remaining epithelium; which leads to thickening, disorganization and cell shedding. At the ulcer margin, the epithelium forms a rolled edge, from the extremity of which a two-layered sheet of flat cells grows over the edematous ulcer bed, and the ulcer site is protected during dilation of the bladder by localized muscle spasm. Healing is effected within about one week, as the mitotic activity declines. Organization of the new epithelium commences at the periphery and the cells acquire glycogen and alkaline phosphatase. Study by SEM, which included normal bladders, confirmed that new epithelium spreads from a rolled epithelial edge, and also showed that cells undergoing rejection have globular profiles with surface microvilli. The immature epithelial cells are markedly distorted from mutual pressure during migration and their surfaces show only short microvilli. Ulcers heal after four to seven days, depending on size, and the new cells rapidly assume the pentagonal and hexagonal outlines and the reticular pattern of surface ridges, characteristic of mature surface cells. The ridges apparently develop by fusion of rows of microvilli. By the tenth day it is difficult to identify the original ulcer site.

The examination of 68 patients with biliary dysfunction determined hypokinesia of the gallbladder in 40, sphincter of Oddi spasm in 15 and combination of the two conditions in 13 patients. Blood biochemical indices showed no differences in patients with biliary dyskinesia compared to normal subjects except for alkaline phosphatase levels elevated in 35.3% of patients. This suggests the development of biliary hypertension and cholestasis. All the patients demonstrated disturbed colloid stability of the bile, in those with combined dyskinesia it became lithogenic. Helium-neon and semiconductor laser radiation of biologically active points and the hepatic region, respectively, improved the patients' performance status. The pain and dyspepsia discontinued. The function of the gallbladder and sphincter of Oddi recovered. Positive changes occurred in the blood and bile biochemistry. Laser therapy promoted bilirubin and bile cholesterol decrease. Cholic acid concentration grew, lithogenic characteristics of the bile returned to normal. It is inferred that laser therapy of biliary dyskinesia proved effective.

The majority of foreign gastroenterologists have their doubts whether there exist "undifferentiated" colitisis. They consider these to be a variant of the irritable bowel syndrome. We have examined 173 patients. Of these, 67 percent were less than 45 years of age with significant intestinal disorders caused by chronic colitis. Diagnosis of Crohn's disease and nonspecific ulcerative colitis had been excluded. The main complaints of the patients were constipations alternated sometimes with short-time diarrhea (61%), diarrhea (13%), spasmodic pains in the inferior parts of the abdomen (20%), abdominal distention, and rumbling (74%). In 79% there was tenderness in the sygmoid colon and caecum and spasm thereof. Rectoromanoscopy (RRS) revealed normal mucosa of the rectum and sygmoid colon in 70%, proctosygmoiditis (predominantly catarrhal) in 30 percent of cases. In proctosygmoiditis (vs the normal mucosa) motor dysfunctions, disorders of the contrast mass passage through the intestine, gaustrations were more often seen but the relief of the mucosa was intact. Results of morphological investigations of biopsy specimens of rectal and sygmoidal mucosas were compared with endoscopy findings. No histological changes were revealed in 23% patients with proctosygmoiditis whereas in cases of endoscopically normal mucosa moderate inflammation was rarely detectable. Inflammatory changes in the mucosa were to be seen more frequently by cytologic analysis than by biopsy but more rarely than by RRS. In this way, 25% patients with endoscopical diagnosis of proctosygmoiditis had normal cytological picture. The increased amount of intestinal enzymes (enterokynase, alkaline phosphatase) in stools does not permit differentiating the functional and organic types of the disease, but it significantly contributes to endoscopical, morphological, cytological, and clinical data. Our investigations show that "undifferentiated" colitis is a rarity and that one finds difficulty in differentiating between the above condition and the irritable bowel syndrome.
