[Spontaneous spinal subarachnoidal hematoma--case report (author's transl)].

"Spontaneous intraspinal canal hematomas' are rare clinical conditions. These are classified as epidural, subdural and subarachnoid. Especially, subarachnoid hematoma is rare only two cases being reported by Bouzarth (1968). We have reported surgical treatment of a female with intraspinal canal subarachnoid hematoma. The patient presented with sudden onset of backpain, followed by paraplegia, sensory impairment and urinary retention. A lumbar tap revealed bloody CSF a complete block. A left vertebral angiography was normal. However, a myelography showed a filling defect at Th5. A laminectomy was performed and a subarachnoid hematoma at the Th1-5 level was completely removed. Etiology of the legion was not identified. The patient made an uneventful recovery. This case suggests that intraspinal canal hematoma needs an operation as soon as possible, especially with urinary retention.

Stomach fermentation in East African Colobus monkeys in their natural state.

The microbial fermentation in the stomachs of two monkeys, Colobus polykomos, collected in Kenya, was studied. The gas accumulated within the stomach contained H(2) but no CH(4). Volatile fatty acid concentrations were high, but accumulated acid prevented determination of the fermentation rate in untreated, incubated stomach contents. Upon addition of bicarbonate, a very rapid rate could be demonstrated. Some D- and L-lactate were in the stomach contents. Starchy seeds or fruits rather than leaves appeared to have been consumed. Microscopically, the most prominent microorganisms seen were large, very refringent cocci, possibly Sarcina ventriculi, and various smaller cocci and rods. The 28 cultured strains of bacteria included 14 Staphylococcus, 2 Streptococcus, 10 Propionibacterium, and 2 Peptostreptococcus. The culture count constituted 10 to 20% of the direct count. No protozoa or cellulolytic bacteria were found.
