This study was aimed to evaluate the masticatory efficiency after botulinum toxin type A (BTX-A) injection during 12 weeks using objective and subjective test. Also, we compared the difference of masticatory efficiency between group that injected into the masseter muscle only (M-group) and group that injected into the masseter and temporalis muscle (M-T group). The mixing ability index (MAI) was used as the objective indicator, and visual analogue scale (VAS) and food intake ability (FIA) index were used as the subjective indicators. It was concluded that masticatory efficiency was significantly lowered after a BTX-A injection into the masticatory muscle, but it gradually recovered in a predictable pattern by the 12 weeks. The disturbance of subjective masticatory efficiency was lasted longer than objective masticatory efficiency. The masticatory efficiency was lower in M-T group than M group. It was statistically significant in the VAS and FIA at 4 weeks, but the MAI showed no significancy. After 4weeks, there was rapid recovery of muscle function in M-T group, and the difference between two groups was not significant. It could be concluded that there will be no serious disturbance of mastication compared to injection is done only into the masseter muscle, even if injection is done into the masseter and temporalis muscle in dose of this study. According to the food properties, it was confirmed that people feel more discomfort on taking hard and tough foods after BTX-A injection and not only hard foods, but also intake of soft and runny foods were influenced by botulinum toxin injection.

This nutrition survey was carried out twice(Spring and autumn) in Sam Chung-Ri, Song Kwang Myun, Soong Ju-Gun. The food intakes of 92 family members were measured by weighing method. Also 45 adults were examined for anthropometric, blood content and blood pressure. The results abtained were summarized as follows; In vegetable foods, the intake of rice was high, but that of legumina and other cereals was low. In animal foods, the intake of milk and eggs was low, and that of oils and fats was very low. However, the food intake between spring and autumn showed remarkable difference. The average intake of calorie, protein, Ca, Fe and vitamin $B_2$ except vitamin $B_1$ and niacin was below the RDAs. The percentage of carbohydrate, protein and fat for energy was 82.2, 11.6 and 6.2%, respectively. The results of anthropometry of height, weight and chestcircumference showed that both sexes Were below Korean Standards. The concentration of Hb & Hct was normal in both sexes, and the rate of anemia was low. The concentrations of plasma glucose, protein, lipids, and blood pressure were normal in both sexes. In case of male, the correlation between plasma albumin and nutrients intake was significant, but the case of female showed different tendency. In case of male, the correlation between weight, height and plasma protein was also significant but the case of female showed different tendency. The rate of parasite infection was very low $(2.17%{\ldots}3.26%)$
