Rectal prolapse in an adult chameleon was surgically replaced. The animal was given tetracycline and dextrose orally, but became comatose 7 days postoperatively and was euthanatized. Necropsy revealed intussusception of the terminal portion of the colon. Phycomycotic hyphae accompanied by necrosis and a mixed leukocytic infiltrate were found in the area of intussusception.

An unusual case of lymphoma is presented in which small bowel intussusception due to a lymphomatous nodule caused an acute abdomen, requiring small bowel resection. Four weeks later a second intussusception caused intestinal obstruction, necessitating a second laparotomy and bowel resection. The high incidence of malignant tumor in adult cases leads us to recommend primary resection without manual reduction in all but rectosigmoid and selected small bowel cases.

Spontaneous intussusception in adults is rare. Recently, we managed two patients with chronic uremia in whom intussusception developed. Histologic examination of the resected segments showed intestinal intramural hemorrhage. We postulate that the coagulopathy associated with uremia may allow for intestinal intramural hemorrhage, thus forming a nidus from which intussusception may be initiated.

A chronic ileo-colic intussusception of an 8 1/2 year old boy did not cause any abdominal complaints. There was a hypochromic anaemia with iron deficiency; occult blood was found in the stoll. Radiographically the lumen within the intussusceptum was extremely narrowed. Following surgery the anaemia disappeared.

Two cases of obstruction of the bypassed small intestine after jejunoileal shunt for obesity are presented. These cases illustrate the possible failure of radiologic visualization of the obstructed bowel since no gas traverses this bowel, as well as two of the possible causes-internal herniation and volvulus. A third cause, intussusception of the blind loop into the colon, has been reported. Obstruction of the bypassed bowel demands surgical intervention and could lead to perforation and peritonitis if untreated. Its prevention involves the closure of all mesenteric defects at the original operation. Surgeons should be aware of the possibility of these conditions in any patient who has had a small-bowel bypass operation.

In two patients with mycosis fungoides the following were found in the region of the eye: Infiltration of the eyelid (sometimes board-like), infiltrations and swellings of the connective tissue, orbital infiltrations (hard as a board) with secondary glaucoma, atrophy of the optic nerve, amaurosis, Descemet spots, cells in the aqueous humour, preretinal opacities of the vitreous body), intussusception of retinal vessels, grey infiltration of the retina.

A case of intussusception of the appendix caused by an adenovillous papilloma in the appendix is reported. The condition was combined with acute appendicitis. The different clinical pictures are described. Due to the varied symptoms the diagnosis of intussusception of the appendix is rarely made preoperatively. The aetiology is briefly discussed. The treatment is operative with removal of the appendix or an appropriate resection.

There were 422 cases of intussusception at the Hospital for Sick Children, Toronto, over a 12-yr period between 1959 and 1970. The histories of all patients who had no pain recorded were evaluated and the duration of signs and symptoms and the treatment required assessed. When compared with those who had pain, it was noted that the children with painless intussusception presented later, hydrostatic reduction was less likely to be effective, and operative reduction and resection was required more often.

Our patient represents an example of acute retrograde jejunograstric intussusception with the additional finding of a bleeding jejunal ulcer in the intussusception. The ulcer may have been etiological in precipitating the intussusception, or a consequence of mucosal sloughing in the hemorrhagic intussusception. Early diagnosis and immediate surgical therapy resulted in an uneventful recovery.

In the multinucleate cap rays of the green alga Acetabularia mediterranea the cell surface increases dramatically within a short time period during the final stages of coenocytotomic cleavage. In early stages of cyst formation the cytoplast is traversed by numerous large and prolate cleavage vesicles which are characterized by typical columellar or spinous coat structures. The cleavage vesicles are closely associated with the surface of plastids and, to a lesser degree, of mitochondria. This intimate association seems to be mediated by regularly spaced, densely stained intermembranous cross-bridge structures and is maintained throughout cleavage. These cleavage vesicles contain a finely fibrillar material structurally similar to the hyaline layer of mucilage that fills the space between the plasma membrane and cell wall. They line up with invaginations of the plasmalemma and vacuole membranes and, together with smaller vesicles interspersed, constitute preformed "perforation lines" for the final separation of the coenoblast portions. Equidistantly spaced plaques of attachment of such vesicles with surface membrane are described. We hypothesize (a) that the cleavage vesicle membrane is the immediate precursor to the new postcoenocytotomic surface membrane, (b) that the cleavage vesicle coat structures are integrated into the subsurface coat of the plasma membrane, (c) that growth of the laterally attached cleavage vesicles by intussusception of small fuzzy-coated vesicles is confined to their "free ends," (d) that the intermembranous cross-bridge elements are related to bristle coat structures and play a role in the establishment of the cleavage lines, and (e) that the coenocytotomic cleavage process is organized so that adjacent plastids are separated in a way that guarantees the inclusion of several plastids in each cyst.
