Laboratory susceptibility tests with various insecticides against houseflies(Musca domestica L.) were simultaneously conducted with larvae. As a result of these experment the following conclusion has been obtained. 1. The relative ratio to various insecticidal effects were naled>DDVP>diazinon>${\gamma}-BHC$>malathion>dieldrin>DDT in houseflies larvae. 2. It was noted that resistance to various insecticides in larvae was in proportion to resistance in adults.

A study for the supplementary diet of the infants and young children of the farming area in Korea has been made. The number of infants and children was 344 aged from 3 months to 2 years and 7 months: the area studied represented one of the stabilized farming areas in this country. 95.6 per cent of the infants were breastfeeding babies, who could not supply any milk products or appropriate supplementary diets. For the improvement of nutritional states of the babies, regional childcare guidance was more urgently needed than social economical problems of this area.

A few reports suggested that guanidine increases the quantity of acetylcholine released from the nerve endings and increases the sensitivity of the end plate to acetylcholine. In this experiment the authors attempted to investigate the influence of guanidine on the acetylcholine effect on the blood pressure of rabbits and excised intestine. The results obtained we re summarized as follows. 1. The hypotensive effect of acetylcholine on the rabbit is augmented by pretreatment with guanidine 5-10 mg/kg. however is inhibited by 20 mg/kg of guanidine. 2. The contractile effect of acetylcholine on the excised intestine of rabbit and rat is potentiated by guanidine.

Authors performed the replantation of the intruded upper right central incisor with the compound fracture of the alveolar process caused by fall down, in particular manipulating the periodontal membrane attached to the root surface or alveolar socket wall with out surgical injury while operation, and observed the good progress clinically and on roengenographs.

The normal lung volumes were determined and subdivided under sitting position in 48 middle school girls, 49 high school girls and 44 house wives. All subjects were free of pulmonary and vascular diseases. The vital capacity was measured by Mckessons spirometer and the residual volume was determined by Rahn's three breathing method. 1. The lung volumes (BTPS) of middle school girls determined were: $RV\;0.59{\pm}0.11l\;FRC\;1.45{\pm}2.22l\;VC\;2.68{\pm}0.29l$ 2. The lung volumes (BTPS) of high school girls determined were: $RV\;0.83{\pm}0.19l\;FRC\;1.9{\pm}0.25l\;VC\;3.15{\pm}0.24l$ 3. The lung volumes (BTPS) of house wives determind were: $RV\;0.95{\pm}0.61{\ell}\;FRC\;2.1{\pm}0.25{\ell}\;VC\;3.06{\pm}0.29l$ 4. The calculated residual ratio $(RV/TLC{\times}100)$ were: $17.7{\pm}2.57%$ in middle school girls and $20.6{\pm}3.65%$ in high school girls and $24.0{\pm}2.31%$ in house wives 5. The functional residual ratio $(FRC/TLC{\times}100)$ were: $43.7{\pm}5.98%$ in middle school girls and $48.8{\pm}4.41%4 in high school girls and $52.6{\pm}5.38%$ in house wives. 6. The correlation coefficients between vital capacity and total lung capacity were r=0.96 in middle school girls and r=0.986 in high school girls and r=0.856 in house wives. 7. The regression equations were obtained follows: $TLC(l) =1.105{\times}VC+0.304$ (in middle school girls) $TLC(l) =1.551{\times}VC-0.902$ (in high school girls) $TLC(l) =0.999{\times}VC+0.954$ (in house wives)
