A pulmonary keratinizing cyst was found incidentally in a 30-week-old female Sprague-Dawley rat. The cyst was lobe of the lung, lined by stratified squamous epithelium and filled with concentric layers of desquamated keratin. The wall consisted of 2-4 layers of well differenciated squamous cells. The adjacent lung tissues were slightly compressed but not otherwise damaged by the cyst. There was no inflammatory reaction or mitotic figures observed in the cyst.

Eight natural or semistynthesized monoterpenes were examined for their effects in rat brain monoamine oxidase(MAO) using benzylamine as substrate. Thujone and 3-carene were found to have the inhibition effects on rat brain MAQ activity, 38% and 95% inhibition at 103M respectively. The kinetic study on 3-carene, the most potent inhibitive type. But (+) pulegon and (-) isopulegon was found to activate MAO slightly.

The physicochemical activities of the underground parts of Roso rugosa Thunb (Rosaceae) , which have been used as an antidiabetic in the folkmedicines of Korea , was carried outThe methanol extract from this plant reduced serum Lipid Level the normal rat . When various fractions from the methanol extract was administered to the rat treated with 1% choholesterol and 0.5% cholic aciddiet , the ethyl acetate soluble fraction lowered the serum triglycerideand phospholipid level most remarkably.

The effects of orally administered ginseng ethanol extract on the calcium release from sarcoplasmic reticulum (SR) calcium pool and on the calcium content in the rat heart perfused with the Langendorff apparatus. The total amount of calcium released from SR calcium pool and the total calcium content in the rat heart were significantly decreased by 43% and 26%, respectively compared with the control.

Effective BuOH fraction was extracted from Puerariae radix (Pueraria thunbergiana), and several pharmacological activities were examined. From several pharmacological examinations, it was found that BuOH fraction has an antipyretic activity against typhoid vaccine pyrexia in rabbit, a papaverine-like antispasmodic activity on isolated ileum and jejunum of rat, an analgesic effects on mice treated by 0.7% HAc, and an anti-inflammatory activity of carrageenin edema in rat. It was found that BuOH fraction has detoxication effects on acute and subacute toxic rat induced by alcohol in consequence of biochemical tests of serum. Therefore it was considered that BuOH fraction has preventive and therapeutic effects in alcohol intoxication.

The inhibitory effects of glipizide on cromakalim-induced relaxation of aortae and hypotension in the anesthetized rats was examined. In rat thoracic aortic rings pre-contracted with norepinephrine, cromakalim produced a relaxation sustainedly. This relaxation was completely inhibited by pre- or post-treatment of glipizide. In the anesthetized rat, cromakalim produced a rapid and sustained fall in the arterial blood pressure. This hypotensive action of cromakalim was abolished by pre- or post-treatment of glipizide. It is suggested that glipizide is the potent inhibitor of cromakalim, $K^{+}$ channel opener, in the rats.

An animal assisted therapy (AAT) for handicapped child's psychotherapy has been reported by some researches. A robot can be substituted for the role of a real animal of the AAT. The robot for the AAT is called RAT (Robot Assisted Therapy). It consists of four parts: microprocessor-based MCU(Micro Control Unit), sensing part with various sensors, the movement part operated by some motors, and the exterior with soft feel. We will here introduce the RAT.

Dopaminergic influences on prolactin release from lactotrophs have been studied using the rat anterior pituitary cell culture. The prolactin inhibiting activity of hypothalamic extracts was examined in relation to dopamine. Dopamine inhibited prolactin secretion from the rat anterior pituitary cell culture in a dose dependent fashion. The median effective dose was $2{\times}10^{-7}$ / M and the maximal inhibition (70-90 % of the control value) was shown by 10$^{-5}$ / M dopamine. Further increase in dopamine concentration did not result in any further inhibition of prolactin secretion.nhibition of prolactin secretion.

Rapid and complete epidermal-dermal separation procedure were determined in neonatal rat skin by light microscopic observation and by compairing enzyme activities in the separated epidermis. Microscopic appearance demonstrated the at four different separation procedures used in the study resulted in good separation of epidermis from dermis` heating method (i.e., immersion in 55C water for 30 sec, followed by immersion in 0-4C water) and microwave irradiation for 10 sec were saving time.
