Rare-earth phosphates are of particular interest because of their catalytic properties associated with the hydrolysis of many aromatic chlorides in the petroleum industry. Lanthanum phosphates (LaPO4) which have been doped with small amounts of copper have shown increased catalytic activity (1). However the physical and chemical characteristics of the samples leading to good catalytic activity are not known.Many catalysts are amorphous and thus do not easily lend themselves to methods of investigation which would include electron microscopy. However, the LaPO4, crystals are quite suitable samples for high resolution techniques.The samples used were obtained from William L. Kehl of Gulf Research and Development Company. The electron microscopy was carried out on a JEOL JEM-100B which had been modified for high resolution microscopy (2). Standard high resolution techniques were employed. Three different sample types were observed: 669A-1-5-7 (poor catalyst), H-L-2 (good catalyst) and 27-011 (good catalyst).

Metronidazole (Flagyl) is an established and effective treatment of urogenital trichomoniasis. J. A. T. Taylor (1964) was using metronidazole to treat a husband and wife for this condition, when she observed the following. The husband, who was a chronic alcoholic, seemed to lose his craving for alcoholic drinks. Sometimes he experienced flushing of the face and shoulders and epigastric discomfort when he took metronidazole soon after alcohol, i.e. he experienced a disulfiram type reaction. The wife reported that alcohol drinks tasted unpleasant to her during therapy. Taylor then studied 53 alcoholic patients and concluded that metronidazole (i) decreased tolerance for alcohol, (ii) diminished craving for alcohol and (iii) produced an uncomfortable reaction to alcohol.

Hypoglycemic symptoms are a very common experience for diabetics ranging from an innocent increased appetite to dreadful unconsciousness. This study was designed to assess the patient’s awareness about the symptoms, experience of individual symptoms and their ability to recognize and to respond accordingly. Materials and Methods: All diabetic patients were assessed for the awareness of different symptoms of hypoglycemia, their experience of individual symptoms in last six months and ability of the patient and family members to recognize and to respond accordingly to these symptoms on a prescribed proforma with the help of trained staff. Results: We had 1260 new cases of DM during the study period with valid diagnosis and taking either sulphonylurea or Insulin who were enrolled in the study. 280 patients had no idea of the symptoms. 564 patients knew no more than three symptoms. Palpitation and sweating were the most commonly known 80% and experienced 65% symptoms. Hunger and epigastric discomfort were the next best known 73% and experienced 58% symptoms. Loss of consciousness was the next in the list in terms of knowledge 52% and experience 23%. Coldness of body 28%, severe weakness 24%, blurred vision 12%, abnormal behavior 12% and altered consciousness 6% were the next in the list of experience. Early morning headache, night terror and frequent awakening were the least known 3% and recognized1% symptoms. Abnormal behavior and altered consciousness were not known to any patient as a symptom. Of those who knew or experienced the symptoms, eating anything available was the most common response, only 35% responded by eating rapidly available food items like sugar, honey, candies, beverages, fruit juice or jams. 3% of patients even resorted to taking diet colas initially and only later took other food after waiting for some time. In the event of patient getting unconscious, 80% of the times attendants did not consider hypoglycemia initially at home at first such experience. Discussion: Patient must be properly educated about these symptoms before prescribing these agents and shall be repeatedly evaluated at each visit. Failing to recognize early and mild symptoms may lead to a terrifying experience.

Graphite powder was treated with lanthanum, aluminum and magnesium phosphate solution, and oxidation resistance of the obtained graphite powder was evaluated. Oxidation starting temperature and oxidation completion temperature of graphite powder treated with various phosphates were 50-100oC higher than those of as-received graphite powder. Graphite powder treated with small amount of lanthanum phosphate exhibited the higher oxidation starting temperature than graphite powder treated with aluminum and magnesium phosphates. LaP5O14 would partially exited on graphite powder, and protect the edge carbon atoms of graphite and reduce the reactivity of carbon atoms toward oxygen, resulting in improving the oxidation resistance.
