Fatty acid and sterol compositions of malagasy tamarind kernel oils

The oil contents of six samples of Malagasy tamarind (Tamarindus indica L.) kernel were determined by hexane extraction (6.0–6.4%) and chloroform/methanol extraction (7.4-9.0%). The protein contents were very low (trace-0.1%). Investigation by gas liquid chromatography revealed 15 fatty acids, mainly palmitic (14–20%), stearic (6–7%), oleic (15–27%), linoleic (36–49%), arachidic (2–4%), behenic (3–5%) and lignoceric (3–8%) acids. Testing for the sterol fraction enabled seven sterols to be separated and quantitatively analyzed by gas liquid chromatography. The main sterols were β-sitosterol (66–72%), campesterol (16–19%) and stigmasterol (11–14%).     

Endoscopic removal of a dental instrument from the stomach: case report

The records of 628 patients admitted to the Joint Study of Extracranial Arterial Occlusion with transient symptoms of carotid system ischemic disease were examined to determine the accuracy of predicting disease of the extracranial internal carotid artery on the basis of clinical information alone. A patient with a history of episodes of amaurosis fugax is more likely to have a lesion of the internal carotid artery on the same side than if he were having only transient cerebral ischemic attacks. In patients with transient symptoms and a carotid bruit on the appropriate side, the incidence of an angiographically normal carotid artery was 15%. In those patients with transient symptoms and no palpable pulsation in the cervical region on the appropirate side, the incidence of an angiographically normal carotid artery was zero.     

Age and features of adrenal cortical function in cerebral circulatory disorders

The indices of glucocorticoid and androgen activity in the adrenal cortex (the level of circulating eosinophils, the daily urine excretion of 17 OCS and 17 CS) and the functional reserve after an ACTH loading was studied in 2 groups of patients with disorders of cerebral circulation under 45 years of age (247 cases) and over 55 (234 cases). In the acute period of a cerebral stroke there was an increase of the glucocorticoid activity which was more definitely expressed in the younger group and a certain inhibition of the androgen function seen mainly in the older group. In transient disorders of cerebral circulation significant age difference in the functioning of the adrenal cortex was not established. In the period following a stroke the established and potential reserves of the adrenocortical glands were distinctly decreased in patients above 55 years and practically unchanged in the younger group.     

Gated blood pool imaging following 99mTc stannous pyrophosphate imaging

Cardiac patients who have undergone 99mTc-stannous pyrophosphate (99mTc-PYP) myocardial imaging can be injected 24 hours later with 99mTc-pertechnetate (99mTc04) to assess left ventricular function. Reduction of 99mTc04 by tin remaining in the blood following the stannous pyrophosphate injection causes labeling of the red cells by 99mTc04 and the creation of a vascular tracer suitable for electrocardiographically gated imaging.     

Mycobacterium tuberculosis infection in two East African oryxes

Tuberculous lesions were observed at necropsy of 2 East African oryxes (Oryx gazella beisa) at a municipal zoological park in Jackson, Ms. Microscopic examination revealed granulomas containing acid-fast bacilli in the lungs and liver of both animals, as well as in the uterus and mediastinal lymph nodes of 1 animal. Mycobacterium tuberculosis was isolated from the tissues of both oryxes and from fluid aspirated from the mammary gland of 1 oryx; the organism was pathogenic for guinea pigs but not for rabbits.
