A one-month old Holstein calf with clinical histories of diarrheal weekness and behavioural abnormality revealed clinical findings of anemia and dehydration. The red blood cells were $1.4{\times} 10^{6}/{\mu}l$ and packed red cell volume was 45%. A blood smear showed a large number of circulating Trypanosoma theileri. To treat Trypanosomiasisi the patient received once a daily oral dosage o$\ulcorner$ 10 mg/kg of the Quinidine sulfate including transfusion (200 ml) for 3 days. After 2 weeks, the calf recovered body condition. These results suggest that Administration of Quinidine sulfate in trypanosomiasis may be a useful treatment approach.

우리나라에서는 1989년 1월 1일 이후 허가된 신약과 동일한 의약품을 제조하거나, 제제개선을 통하여 흡수율을 향상시키는 경우 등에 있어서 생물학적 동등성 시험을 실시하여 두 제제간의 생체이용률을 비교하도록 규정되어 있다. 다른 나라에서도 신약과 동일한 의약품을 허가 받고자 할 경우나 대체조제를 위한 복제의약품의 생산 시 생물학적 동등성 시험자료를 제출하도록 하고 있으며, 이에 따른 생물학적 동등성 시험 기준을 운영하고 있다. 최근 각국에서는 국제적 조화를 이룬 기준을 마련하고자 하는 추세이다. 현재 우리나라에서는 의약분업 실시에 따라 생물학적 동등성 시험의 중요성이 부각되고 있으며 국제적인 수준에 맞추어 관련 기준을 개정해야할 필요성이 대두되고 있다. 캐나다에서는 1992년에 처음 생물학적 동등성 시험 기준을 공표하여 평가하고 있다. 본 논문에서는 캐나다의 생물학적 동등성 시험 기준을 소개하여 현행 규정과 비교 검토함으로써 생물학적 동등성 시험 기준을 보다 과학적이고 윤리적이며 합리적인 규정으로 개정하기 위한 자료로 활용하고자 한다.

The mammary excretion of suphamethomidine after intravenous and/or oral administration was investigated in cow. The results show that sulphamethomidine is bound to plasma proteins to a great extent (80~90%). Ay a dosage of 60 mg./kg. maximal concenration in plasma of this sulphonamide was reached 7-10 hours after oral dosing. The sulphonamide concentration in plasma slowly declined after both oral and intravenous administration (fig. 1, 2, and 3) The concentration of sulphonamide in milk was very low and the excretion was completed in 7 days after a single oral dose and 5 days after intravenous injection while in the case of blood plasma it was 11 and 7 days, respectively. In addition, the renal excretion of sulphamethomidine was investigated while under continuous intravenous intravenous infusion. The excretion ratios varies according to self depression (table. 1). Blockade of the tubular secretion with diodone lowered the excretion of sulphamethomidine. It is concluded that the renal excretion of sulphamethomidine in cows occurs by filtration by slight tubular secretion and also by a high rate of back diffusion.

Accelerated stability testing was performed on the different 7 dosage forms in order to evaluate the influences of the existence of other vitamins, minerals, excipients on the chemical stability of vitamin A in complicated vitamin drug products. The stability results suggested that increasing of storage time and temperature has resulted in increasing the rate of vitamin A decomposition and the shelf lives(t$\sub$90/) under the test decreased as the storage temperature increased.

Drug excipients are material used in the formulation of pharmacologically active drugs. They have a variety of roles including dilutents/fillers/bulking agents, binders/adhesives, propellant, disintegrants, lubricants/dlidants, colors, flavors, coating agents, polising agents, fragrance, sweeteening agent, polymers and waxes. Excipient should be inert or inactive and does not interfere with the test. Nowadays within industry there has been a recent surge of interest in novel excipient for novel dosage forms. The purpose of the review is to introduce the administration systems of drug excipient about kinds, matters to be attended to change of excipients.

Docosahexaenoic acid (DHA) rich oil was obtained from blue fin tuna (Thunnus thynnus orientalis) orbital tissue with centrifugation of 12,000 rpm under vaccum $(10^{-1}\;Torr)\;at\;4^{\circ}C$. The effect of DHA rich oil (DHA content; $27.8\%$) on $CCl_4-induced$ acute injury was investigated biochemically and histopathologically. Dosage of DHA rich oil on 24h before $ CCl_4-administration$ prevented significantly the increase of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GTP) values. No necrosis of hepatocytes was observed in rat livers treated with DHA oil on 24h prior to $CCl_4-administration$. These results suggested that DHA oil controls the accumulation of fat in the liver and prevented the liver injury.

Adverse events such as hemoptysis and gastrointestinal hemorrhage during tyrosine kinase inhibitor treatment are relatively rare, but the severity of the bleeding can be higher than other common adverse events. It is necessary to educate patients about its possibility so that they can be found early. In this case report of radioiodine refractory thyroid cancer patient, hemoptysis and gastrointestinal bleeding has occurred following lenvatinib administration. Drug interruption and dose modification and dose interruption were required in addition to management for bleeding itself. It is necessary to confirm the high risk of bleeding before the administration of tyrosine kinase inhibitors, and to appropriately control the follow-up interval and drug dosage accordingly.

The microcapsules of amoxicillin using stearyl alcohol and polyethyleneglycol 8000 (PEG 8000) were prepared by a emulsion melted-cooled process in water phase. The size distribution, dissolution test, observation with SEM and in vivo test were investigated. The microcapsules obtained were spherical, uniform and free flowing particles. The release of drug from microcapsule was increased in proportional to the content of PEG 8000. As the PEG 8000 content increased, the particle size of microcapsule was decreased. Sanning electron micrograph study revealed that microcapsules had comparatively rough surfaces as drug content was increased. The $AUC_{0-12}$ after administration of amoxicillin microcapsules was more increased 40% as compared with the AUC after administration of amoxicillin powder in rabbits.

DA-8159 is a new PDEV (Phosphodiesterase V) inhibitor, synthesized by Dong-A Pharm., as an oral agent to treat male erectile dysfunction. To make a selection of the dosage of oral administration in carcinogenic studies, we studied preliminarily the pharmacokinetics of DA-8159 after single (at the 1$\^$st/ day) and 1-week (at the 7$\^$th/ day) oral administrations of the drug at doses of 15, 50 and 150 mg/kg/day, to male ICR mice. In 15mg/kg single and 1-week repeated oral administration groups, the concentrations of DA-8159 and DA-8164(the main metabolite of DA-8159) were below the limit of quantitation(LOQ:50ng/ml).

Flowery Knotweed Root is the dried tuberous root of the knotweed family wheres Auriculate Swallowwort Root is the dried tuberous root of the swallowort family. Flowery Knotweed Root is also called Red Flowery Knotweed Root in China, which is dried root of Polygonum multiflorum THUMB. Chinese Flowery Knotweed Root is better known as the dried tuberous root belonging to the family Apocynaceae whereas White Flowery Knotweed Root in Korea is the dried tuberous root of Cynanchum wilfordii(Maxim) Hemsl. Up to now, while the dried root named Red Flowery Knotweed Root has been widely used in China, Auriculate Swallowwort Root has been widely used in Korea. Both the roots contrast in a striking way with the origin, shape, botanical names, other names, and chemical constituents, so administration and dosage without discrimination of both sides can be open to question. According to the literature, it is recorded that Flowery Knotweed Root and Auriculate Swallowwort Root are similar to the characteristics, properties, and actions. From this study, the result is as follows: 1. Flowery Knotweed Root and Auriculate Swallowwort Root are divided into the family Apocynaceae and the family Polygonaceae, respectively. Accordingly 2. Flowery Knotweed Root is in shape of an irregular spindle and looks reddish- brown or deep reddish-brown and the section is light yellowish-brown, while Auriculate Swallowwort Root looks yellowish-brown and the section is white or yellow. 3. Flowery Knotweed Root is reported by the Journal of the Crude Drug that the medicinals have not the same therapeutic action as Auriculate Swallowwort Root. It is recorded that the properties, channel entry, functions of Flowery Knotweed Root and Auriculate Swallowwort Root in literature have much in common. Many works on the roots of this plant has been used traditionally as a tonic are required of. In view of the results, Flowery Knotweed Root and Auriculate Swallowwort Root varies both in nature and in shape, so that the administration and dosage of the medicinals must be taken a prudent attitude.
