  • As a study to elucidate whether taste buds contain specific proteins, rat dorsal lingual epithelium was analysed by electrophoresis. The epithelium of the vallate papilla (with numerous taste buds), the area of the fungiform papilla 9with a few taste buds), and the area between vallate papilla and large filiform papilla (not containing taste buds) were strippled off by treatment with 0.7% EDTA. The epithelial protein was extracted by 1% SDS and 1% Mercaptoethanol in 0.01M phosphate buffer (pH7.2). Extracts were analysed by disc SDS-PAGE. Because the patterns of protein composition from each site were similar with each other as a whole, it is concluded that taste buds do not contain specific protein detected by SDS-PAGE in adult rat. But a protein on M.W. 49000 which lies in the area of molecular weight of keratin molecules was found only in the epithelium containing taste buds. This results suggested that the epithelium containing taste buds differentiate dissimilarly to the epithelium not containing taste buds.

  • Objectives: This study evaluated the correlation between taste function and spleen qi deficiency in patients with burning mouth syndrome (BMS) and compared subgroups of BMS (i.e., dysgeusia and non-dysgeusia subgroups). Methods: This study included 60 participants categorized into two groups: a BMS group and healthy control (HC) group. Taste threshold was measured within six levels using solutions of four basic taste qualities. Subjects' Oral Health Impact Profiles (OHIPs-14) and Spleen qi Deficiency Questionnaire (SQDQ) scores were analyzed. Results: Taste thresholds for sweet (sucrose) and salty (NaCl) tastes were significantly lower in the BMS group than in the HC group, but sour (citric acid) and bitter (quinine HCl) tastes showed no significant differences between groups. In the dysgeusia and non-dysgeusia subgroups, no significant differences in the four basic taste thresholds were found. SQDQ scores were significantly higher in the BMS group compared to the HC and in the dysgeusia group compared to the non-dysgeusia group. OHIPs-14 and SQDQ scores for the BMS group were significantly and positively correlated. Conclusions: Spleen qi deficiency is related to taste function and can be used to treat BMS patients with taste dysfunction.

  • The effect of hot taste preference on selected immune responses was investigated in human peripheral immunocompetent cells. Human lymphocytes and natural killer(NK) cells were prepared at a concentration of 2$\times$$10^{6}$ cells/ml in RPMI-1640 containing 10% fetal bovine serum. Lymphocytes proliferation was determined with the [$^{3}H$]-thymidine pulse for 18hrs after concanavalin A, phytohemagglutinin, Salmonella typhimurium mitogen, or media alone. NK cell activity was measured by cytolysis of $^51Cr$-labeled target cells K562. Serum antibodies levels such as IgM, IgG, IgA were also measured by ELISA method. There was no difference of serum IgM level among the groups, but IgG and IgA levels were greater in the group with hot taste preference than those of the group without hot taste preference. In lymphocytes of the group with hot taste preference there was a greater mitogen-induced lymphocyte proliferative responses compared to the group without hot taste preference. In addition, NK cell activity in group with hot taste preference was lower than that of the group without hot taste preference. These results suggest that the eating habit of spicy food containing hot components may affect immune status by modulating selective immunocompetent cells function.

  • The effect of glossopharyngeal nerve transection on the taste buds of the rat vallate papilla was examined by using the method of DNA nick-end labeling (TUNEL) and standard electron microscopic technique at 1, 3, 5, 7, 9 days after denervation. In general, the number and size of taste buds decreased as more days passed after denervation. They started decreasing on day 3 post denervation and virtually all taste buds were disappeared on day 9 post denervation. In studies using TUNEL method, TUNEL postive cells markedly increased in their numbers one day post denervation, as compared with controls. The number of apoptotic taste bud cells per taste bud profile was averaged to be 0.64 and 0.44 for day 1 and 3 post denervation, respectively, whereas it was 0.10 in controls. In electron microscopy, apoptotic cells were identified by the presence of condensed and fragmentary nuclei in a cytoplasm, which resulted in increased density. In control rats, only few apoptotic cells were found. On days 1 and 3 post denervation, nerve fibers almost disappeared from the taste buds and some apoptotic cells were apparent. On days 7 and 9 post denervation, a few taste bud cells were still present in the epithelium of the bottom of the trench wall of the vallate papilla and most of them showed apoptotic changes. The results indicate that the death of taste bud cells in normal conditions is controlled by apoptosis and the decrease and disappearance of taste buds after denervation is also caused by apoptosis of taste bud cells.

  • In order to get taste sensation 116 male and 82 female subjects were tested by dropping solution on tongue. Table I shows the number of subjects in each selected age group. none of the subjects complained gastrointestinal discomforts and drinking and smoking habits were moderate (Less than 5 cigarettes a day). Taste sensation was elicited by applying standard tap water solutions of sucrose(sweet), , sodium chloride(salty), citric acid (sour) and quinine (bitter) on tongue. The dour concentrations of each solution are given in Table 2. The test were done about 1 hour after meal . A drop of approximately 0.1 ml of the lowest concentration of solution was placed on tongue. The number of subjects who recognized the taste of concentrations were recorded in each age group. The obtained results were as follows ; 1. The sweet taste sensation of each age group was more sensitive in female than in male. 2. Decreased level of sensitivity to sweet. salty, sour and bitter taste was detected in the 40 year age group. 3. Females tent to be more sensitive to taste than males generally.

  • The present study demonstrates the first-ever characterization of cell types that express the vanilloid receptor 1 (VR1) in the taste buds of rat circumvallate papillae. We performed electron microscopy to identify the subcellular location. The VR1 immunoreactivity was associated with the endoplasmic reticulum, cytoplasmic vesicles, and plasma membrane of taste cells. These results demonstrate the localization of the VR1 in membranous structures of the taste cells. We used double immunofluorescence histochemistry with taste cell type-specific markers to identify the cell types that express the VR1. The VR1 was detected in all functional taste cell types (Type I, Type II, and Type III cells). Together, our data suggest that the VR1 might play different roles according to the cell types within a taste bud.

  • Richadella dulcifica, a native shrub in tropical West Africa, gives red berries that have the unusual property of modifying a sour taste into a sweet taste. The red berries contain a taste-modifying protein named miraculin. A synthetic gene encoding miraculin was placed under the control of constitutive promoters and transferred to lettuce. High expression of miraculin was obtained, with accumulation of up to 1% total soluble protein in lettuce leaf. In addition, the miraculin expressed in lettuce possesses a taste-modifying activity.

  • 본 논문은 취미의 자발적인 도야가 어떻게 가능하고, 도야된 취미를 갖는 것이 왜 성품의 교화와 문화 발전을 위해 필요한지 그 이유를 밝힌다. 이는 취미가 자신의 판정을 항상 '쾌'로 반성하는 것과 관련이 있다. 취미는 자신의 판정의 타당성을 검사할 때마다 보편타당한 근거를 발견하는데, 이러한 '발견의 기쁨'이 취미를 자발적으로 도야하게 만드는 것이다. 도덕적 성품을 갖기 위해서는 자신의 행위의 도덕성을 스스로 평가해 보는 훈련이 필요하고, 시대를 대표해 계승할 만한 작품을 선별하기 위해서는 높은 안목이 필요하다. 그러나 우리는 작품의 미를 평가하면서 이러한 자율적 사고를 즐겁게 습관화할 수 있다. 본론에서는 이 같은 사실을 칸트가 <연역>에서 제시한 세 가지 부정적 취미판단의 사례를 통해 규명하려고 한다. 칸트에 따르면 부정적 취미판단은 현재 아름다운 작품이 불쾌감을 준다는 뜻이지만, 이를 통해 주장하는 것은 취미가 도야되었다는 것이다. 필자는 세 가지 사례에서 드러난 취미의 반성 방식을 '버티기', '결함 지적하기', '스스로 번복하기'라는 도야방식으로 정식화한다.(2장) 그리고 이를 통해 이러한 취미의 도야 방식은 이성이 도덕적 관심을 갖도록 자극함으로써 인성의 교화에 영향을 줄 수 있다는 점에서(3장) 그리고 문화 계승의 산물을 취미가 직접 심사한다는 점에서 취미의 도야가 필요함을 역설한다.(4장) 본론 마지막 장에서는 이것이 어떻게 가능한지를 규명하기 위해, 취미의 반성방식을 좀 더 근원적으로 탐색해본다.(5장) 특별히 실러의 '유희충동' 개념을 빌려 그 이유를 밝히는데, 그의 설명은 취미의 발견의 기쁨이 주는 역동성을 이해하는데 도움을 주기 때문이다. 취미는 대립하는 마음의 활동에서 서로의 활동을 '추동'하는 근거를 발견하고, 이러한 자기 활동에 스스로 고무되는 특징이 있다. 말하자면 취미는 작품이 불만족스러운 상황에서도 유희충동을 '만들어내기' 때문에, 즐겁게 앞의 두 과제를 감당하도록 마음을 촉진하는 것이다. 결론에서는 그런 의미에서 취미에 의한 유희충동은 창작을 통해 극대화된다고 보고, 창작하는 예술가처럼 이를 직접 체험할 수 있어야 함을 밝힌다.(6장)
