A spin-label study of protein-lipid interaction in sarcoplasmic reticulum of rabbit skeletal muscle.

Whether or not the thermotropic change at about 18 degrees C in the physical state of Ca2+-ATPase protein molecules of sarcoplasmic reticulum membranes could be transmitted to lipids through protein-lipid interactions was investigated using a spin-label technique. Fatty acid spin labels were used to probe the bulk membrane lipids while long-chain spin labels attached at one end to the Ca2+-ATPase molecules through a covalent bond were used to monitor the boundary lipids. The results on the temperature-dependence of alkyl-chain flexibility of lipid molecules indicate that the change in the state of the protein molecules is accompanied by one of the boundary lipids, but not of the bulk lipids.

Five-year follow-up study of patients with persistent vegetative state.

One hundred and ten patients with persistent vegetative state, were followed up for a period of five years from 1973 to 1978. Seventy-three per cent of the patients died during the period while about 10% of them recovered partially from the vegetative state. Among the recovered patients, only three became able to communicate, but two of these are not independent for their daily activites. Reactivity and clinical symptoms of 30 survivors were examined, but no great changes occurred during the last two years of the study.

The specific binding of parotin on duct cells of human parotid gland.

The relationship between parotin and human parotid gland was investigated using indirect technique of enzyme antibody method. Normal rabbit IgG has non-specific affinity to duct cells of human parotid gland, but it was suppressed by adding bovine serum albumin. Anti-parotin rabbit IgG has no reaction products on the sections of adult human parotid gland. When the sections, initially incubated with parotin solution in PBS, were treated with anti-parotin rabbit IgG containing bovine serum albumin, and then HRPO-labeled anti-rabbit gamma globulin antibodies (swine IgG), intercalated and striated ducts excepting excretory ducts were stained with diaminobenzidine reaction, but also acinar cells did not. These results indicate that parotin is bound specifically on duct cells of human parotid gland.

Pineal apoplexy.

A case of haematoma in the pineal region is reported in a patient whose initial symptom was subarachnoid haemorrhage. The encapsulated haematoma and surrounding blood clots were removed surgically. Haemorrhage into a pineal cyst may have been the cause of this particular intracranial mass.
