Effect of 2,4- D application on the fruit maturity and quality of 'Harcot' apricot and 'Mibaek' peach was examined. Leaf area of 'Harcot' apricot was not affected by 2,4-D while that of 'Mibaek' peach was increased by 35mg · L-1 2,4-D. Application of 2,4-D at 35mgㆍL-1 increased the fruit weight of both species, and that of 'Harcot' was doubled. Soluble solids content of 'Harcot' was decreased by 2,4-D while that of 'Mibaek' was not affected. Fruit maturity of 'Harcot' and 'Mibaek' was enhanced for respective 4 and 1 day by 2,4-D application. Percent fruit cracking of 'Harcot' apricot was decreased by 35mg · L-1 2,4-D.
지베렐린과 에세폰의 葉面撒布가 '美白' 복숭아의 熟期와 品質에 미치는 影響

In order to obtain the basic data for artificial maturity control of 'Mibaek' peach, GA and ethephon were foliar sprayed 4 weeks prior to harvest, and their effects on fruit maturity and quality were examined. GA and ethephon tended to decrease the fruit weight except 100mg ㆍ L-1 GA+50 to 100mg · L-1 ethephon treatment. GA increased the fruit firmness, and ethephon at higher concentration increased the fruit drop. Harvest date was advanced for 7 to 8 days by ethephon while was delayed for 6 to 8 days by GA treatment, regardless of concentration.

The spr D gene encoding Strptomyces griseus protease D(SGPD); a chymotrypsin-like proteae, was cloned from Strptomyces griseus IFO13350 and sequence. Most of the amino-acid sequence deduced from the nucleotide sequence is idential to that Strptomyces griseus IMRU3499 except that one amino acid has been deleted and Trp 369 has been substituted into Cys369 in the SGPD from S. griseus IFO13350 without affecting the protease activity. The spr D gene was overexpressed in Streptomyce liv-idans TK24 as a heterologous host. Various media with different compositions were also used to max-imize the productivity of SGPD inthe heterologous host. The SGPD productivity was best when the transformant S. lividans TK24 was cultivated in R2YE medium. The relative chymotrypsin activity of the culture broth measured with an artificial chromogenic substrate, N-scuccinyl-ala-ala-pro-phe-p-nitroanilide, was 16 units/ml. A high level of SGPD was also produced in YEME and SAAM medial but it was relatively lower that in R2YE medium and negligible amounts of SGPD were produced in GYE, GAE and Benedict media. The growth of S. lividans reacted the maximum level of cell mass at days 3 and 4 of the culture, but SGPD production started in the stationary phase of cell growth and kept increase in till the 10$^{th}$ day of culture in R2YE and YEME medium, but in GYE media the productivity reached maximum level at 8days of cultivation. The introduction of the spr D gene into S. lividans TK24 triggered biosyntheis of the pigmented antibiotic , actinorhodin, which implies some protease may paly a very improtant role in secondary-metabolite formation in sStreptomyces.
진성 골격성 Ⅲ급 부정교합에서 두개저, 상악, 하악의 위치 및 크기에 관한 연구

The facial patterns were expressed by the interrelation of variable factors such as heredity, function and environment. Such variable factors have an effect on the growth and development of maxillofacial bones. The malocclusions with skeletal discrepancies are caused by abnormal forms, sizes and positions of cranial base, maxilla and mandible. For the proper diagnosis and treatment planning, the analysis of such structures is necessary. Lateral cephalograms of 54 adults with class Ⅲ malocclusion patients (test group) and 61 adults with normal occlusion (control group) were analyzed. Anteroposterior relations and sizes of cranial base, maxilla, mandible were estimated to compare with those of normal ones. In test group, the anterior cranial base length was within normal range, but posterior cranial base, maxilla and mandibular body were longer than those in control group, significantly. Based on the cranial base, the location of maxilla in test group was normal, but the location of mandible was more anterior than that in control. Based on the maxilla, the location of mandible was more anterior in test group than that in control. Both mandibular body and ramus anteroposterior lengths in test group were larger than those in control. Both mandibular plane angle and upper gonial angle were within normal range, but lower gonial angle was significantly high in test group.
Sensitization of Vanilloid Receptor Involves an Increase in the Phosphorylated Form of the Channel

A vanilloid receptor (VR1, now known as TRPV1) is an ion channel activated by vanilloids, including capsaicin (CAP) and resiniferatoxin (RTX), which are pungent ingredients of plants. Putative endogenous activators (anandamide and metabolites of arachidonic acid) are weak activators of VR1 compared to capsaicin and RTX, and the concentrations of the physiological condition of those activators are not sufficient to induce significant activation of VR1. One way to overcome the weak activation of endogenous activators would be the sensitization of VR1, with the phosphorylation of the channel being one possibility. The phosphorylation of VR1 by several kinases has been reported, mostly by indirect evidence. Here, using an in vivo phosphorylation method, the VR1 channel was shown to be sensitized by phosphorylation of the channel itself by multiple pathways involving PKA, PKC and acid. Also, in sensitizing VR1, BK appeared to show activation of PKC for the sensitization of VR1 by phosphorylation of the channel.
