Anatomical considerations of selective pudendal neurectomy

The pudendal nerve was examined in 100 cadavers of both sexes. Because of the variable number of trunks of the pudendal nerve, 5 types were distinguished: one-trunked; two-trunked, rectopudendal; two-trunked, pudendo-penile (or-clitoridal); three-trunked, recto-perineo-penile (or-clitoridal); four-trunked, recto-perineo-perineopenile (or-clitoridal). The authors' suggestions make it possible to perform selective pudendectomy, consisting in denervation of the sphincter urethrae muscle by neurectomy of the perineal branches of the pudendal nerve.     

Endoscopic papillosphincterotomy in patients with para-ampullar diverticulosis

It is suggested that the numerous variants of diverticula occurring in the region of the major duodenal papilla should be grouped into four types. Type I--the major duodenal papilla (MDP) is on the floor of the diverticulum; type II--the MDP is in the region of the lower ++semi-circumference of the diverticular orifice while the longitudinal fold runs radially on the wall of the diverticulum; type III--the MDP is in the region of the orifice of the diverticulum while the longitudinal fold does not pass on its wall; type IV--two diverticula located above the MDP to both sides of the longitudinal fold. Endoscopic papillosphincterotomy is considered contraindicated in patients with type I diverticulum. When indicated, the intervention was carried out in patients with types III and IV diverticula. Endoscopic papillosphincterotomy can be conducted in patients with type II diverticulum measuring more than 2 cm.     

Intraportal allogeneic transplantation of the islets of Langerhans cultures in the complex treatment of surgical patients with diabetes mellitus

The article presents results of treatment of 21 patients with a surgical pathology and diabetes mellitus who had intraportal allotransplantation of cultures of islet cells of the pancreas and 316 patients with the similar surgical pathology without such transplantation. It was found that the intraportal introduction of islet cell cultures into the liver can result in an early and considerable drop of the injected insulin dose which is very important in the postoperative period. This method allowed to make the period of treatment at the hospital approximately 15 days shorter.     

Subtypes of the Gc gene (vitamin D binding protein) in the Polish population

Gc subtypes were analyzed by isoelectric focusing on thin-layer polyacrylamide gel. In the sample of the Polish population including 278 persons, six Gc phenotypes were encountered: 1S, 1F-1S, 1F, 2-1S, 2-1F, 2 with the following frequencies: 0.342, 0.151, 0.014, 0.360, 0.072 and 0.061. Frequency of Gc1S was 0.597, Gc1F - 0.126 and Gc2 - 0.277. It was shown that a group system of the Gc protein in the Polish population was in good agreement with Hardy Weinberg equilibrium.     

Angiomyolipoma of the kidneys

59 angiomyolipomas were studied: immunohistochemistry (IHC) was used in 24 cases, electron microscopy (EM) in 6 cases. 57 tumors had a typical structure, 2 did not contain fat component. Premelanosomes were found by EM in one tumor. Smooth muscle actin was found in all tumor cells. Involvement of lymph nodes was observed in 2 patients. Histogenesis of this tumor is discussed.     

Morphochemical characteristic of rat brain structures after exposure to delta-sleep inducing peptide following long-term amphetamine administration

The aim of this work, that was carried out using Wistar rats, was to characterize the response of neurons of different morphofunctional types to amphetamine administration and to study the possibility of correction of these changes by delta-sleep inducing peptide (DSIP). Single intraperitoneal injection of 60 microg/kg of DSIP following a long term amphetamine administration (2.5 mg/kg for 3 weeks) was shown to result in normalization of brain metabolism, that was disturbed by the drug. The correcting DSIP effect was found in rat brain structures judging by the parameters of the state of proteins in neurons of sensomotor cortex and caudate nucleus and by the activity of enzymes of neurotransmitter metabolism, such as type A and B monoamine oxidases and acetylcholine esterase, that was determined in subfractions of the same brain structures. DSIP modulating effect in phenamine stereotypy supports its role as an adaptogen of intercenter relations in CNS pathology.
