Clobazam is one of the benzodiazepine compounds consisting of different structure compared to previously marketed other benzodiazepines. In rescent days, the antiepileptic effects of this drug has been recognized and used in epileptic patients. To confirm the efficacy and side effects of clobazam, we review the records of the 60 patients who was medicated clobazam more than 9 months. These patients had complex partial seizure with unsatisfactory control despite of adequate drug dosage and duration. Among these patients, the improved one were 23 (38. 3%), and tolerant one were 25 with 5.6 month mean remission duration. Only the 7 of 60 patients complained the adverse symptoms and this were not serious enough to discontinue medication. In conclusion, clobazam is relatively safe and efficacious medication enough to try for patients with unsatisfactory seizure control.

Basing on common chemical reactions, thin layer chromato graphy, absouptive ultraviolet spectrum some parameters were determined for preparation containing benzodiazepine in HCM City. The efficiency of extraction of benzodiazepan in 6 self made sample: Rhino sweet drink, coca-cola, combined food, soya milk, 333 beer and urine. Results found 17 active substances of diazepine group in 131 specialities of commercial propriatary name in HCM City, where diazepam had accounted higher rate in narcotic intoxixation cases. In criminal cases involved in tranquillisant narcotics, the most common substance were diazepan, flunitrazepan, clonazepan, bromazepan, alprazolam, clorazepat, oxazepan and nor-diazepan

In 54 cases with heterophoria, the effects of the tranquilizers were studied. The minimum doses of two kinds of tranquilizers i.e., phenothiazine derivative (chlorpromazine) and benzodiazepine derivative (oxazepam) were given for 3 days. The results were as follows: 1. In 18 cases (43%) of the 30 cases who complained asthenopia, the symptom was relieved to some extent. The improvement of the symptom occurred with decrease in the Jateral phoria in 13 cases, and with increase in fusional amplitude in 13 cases. 2, There were no changes in the lateral phoria in 31 cases (59%) at distance, but at near, in 27 cases (52%) there was decrease in the lateral phoria. The amount of the increment or decrement in prism diopters was somewhat larger at near than at distance, and also somewhat larger in cases, in which the initial lateral phoria before medication is high, than in the cases with low initial lateral phoria. 3, There were no changes in the fusional amplitude in 24 cases (46%) at distance, but at near, in 28 cases (55 %) there was the increase in fusional amplitude. The changes in the amount of the increment or decrement in the fusional al1}plitude were similar to that of the changes in the amount in lateral phoria. 4, There were no remarkable changes in vertical phorias. 5. In exophoria there were no remarkable differences between subjects given chlorpromazine and those gIven oxazepam.

Posthypoxic myoclonus is poorly controlled with current treatments. Based on clinical experience, valproate and benzodiazepines have been used to treat myoclonic seizures. Rarely, some antiepileptic drugs may exacerbate myoclonic seizures. Although lamotrigine is controversial for treatment in myoclonic seizures, we experience a case of posthypoxic myoclonus improved with lamotrigine add-on therapy.

The effects of lorazepam on cerebral function, metabolism, and hemodynamics were studied in eight dogs receiving a general anesthesia with isoflurane(0.5 vo1%)-50% nitrous oxide-oxy-gen. The effects of benzodiazepine antaronist, flumazenil, were also examined. Lorazepam(0.5 mg/kg) administration did decrease mean arterial pressure(MAP) and herat rate(HR). It did significantly decrease cerebral blood flow(CBF)(measured by posterior sagittal sinus outflow method) by 25% of control value(68+/-l3 vs. 51+/-12ml/100gm/min, meanSD) and cereberal metabolic rate for oxygen(CMRO ) by 17% (3.96+/-1.04 vs. 3.30+/-0.92ml/l00gm/min, mean+/-SD). Electroencephalogram(EEG) converted to high amplitude, predominantly theta and delta activity. Intracranial pressure(ICP) increased markedly. Following flumazenil(0.06 mg/kg) administration, HR recovered completely to control level but MAP increased only at 5 min. compared to pre-flumazenil value and returned to pre-flumazenil level. CBF recovered to control level for 15 min. and deereased after 30 min. compared to control level but higher than pre-flumazenil level about 9-15%. CMRO recovered completely to control leveL EEG changed to an awake pattern after fluamzenil administration. It is concluded that lorarepam decreased cerebral function and metabolism and depressed hemodynamic fuction. Benzodiazepine antag- onist, flumazenil, was effective in reversing cerebral and hemodynamic effects, may be in dose related manner.

The novel antipsychotic, olanzapine, has structural and pharmacological properties similar to clozaine. Antipsychotic drugs, as well as mood stabilizers, can cause neutropenia, which can progress to life-threatening agranulocytosis if the medication is not discontinued. We report two cases of reversible neutropenia associated with a olanzapine-valproate combination treatment. This report suggests that patients treated with the combination of olanzapine and valproate should be monitored for the occurrence of leukopenia and neutropenia.

It has recently been reported that chemical evaluations of a new benzodiazepine derivative, flunitrazepam (Ro 5-4200) revealed promising effects as premedicant. We studied on effects of premedication by double blind technique comparing flunitrazepam (Ro 5-4200) 0.03mg/kg I.M. and meperidine HCI 1mg/kg I.M. in 300 cases of preoperative patient by random selection. The questionaire on drowsiness, sleepiness and awareness during transport to the operation theatre, as well as nausea and vomiting were checked by anesthetists who were ignorant of the given premedicant. Following results were obtained; 1) Flunitrazepam has excellent calming effects in preanesthetic period, inducing drowsiness and adequate rest. 2) Flunitrazepam produces good sleep the night before operation. 3) Flunitrazepam has lower incidence of nausea and vomiting than that cf meperidine HCI.
