1.The Affinity of Calmodulin-Affigel for Inositol Triphosphate Kinase From Bovine Brain.
Yeungnam University Journal of Medicine 1990;7(1):39-50
The one event on signaling mechanism is the cleavage by adenyl cyclase of ATP into second messenger, cyclic AMP. The other transfer system of inositol metabolism, it is widely recognized that hydrolysis of the minor membrane lipid phosphoinositide bisphosphate (PIP₂) initiated by occupation of certain receptors and catalyzed by phospholipase C, lead to toe generation of the two intracellular messengers, inositol triphosphate (IP₃) and diacylglycerol (DG). IP₃ is converted to inositol tetrakisphosphate (IP₄) by IP₃ kinase. In the present study, it is that purification of calmodulin is used by phenyl-Sepharose CL-4B chromatography, it's molecular weigh, 17,000 in SDS-polyacrylamide gel electrophoresis. In order to observe the affinity between calmodulin (CaM)-Affigel 15 and IP₃ kinase, and isolated IP₃ kinase, was applied in CaM-Affigel with Ca²⁺ equilibrium buffer and EGTA equilibrium buffer. We compared with binding and elution effect of IP₃ kinase in several condition of buffer. In affinity of binding, Ca²⁺ equilibrium buffer was in the most proper condition, and elution, CaM/Ca²⁺buffer (CE 1 10.36, CE2 12.76pM/min/mg of protein) was effected much more than EGTA buffer (E2 1.48, E 2.43pM/min/mg of protein), but CaM/Ca²⁺stimulate the activity of IP₃ kinase. And then, several detergents such as sodium deoxycholate, tween 20, cholic acid, polyethylene glycol, chaps were applied. The 0.2% chaps buffer (E2 23.19, E3 8.05pnM/min/mg of protein) was the most effective in elution of IP3 kinase.

Leiomyomas are the most common benign tumors of the uterus, and although they can occur at any site in the genitourinary tract, they very rarely originate from the urinary bladder. We report a case in which a leiomyoma occurred at that site, deseribing the US, CT, and MRI findings.

A study of the volume and linear measurements of the breast to determine new nipple positions for 142 subjects was undertaken. Volume determination was done by using the Grossman-Roudner device. The size and shape of the female breast may differ significantly, and such size and linear measurements have to be measured accurately prior to breast aesthetic surgery. Statistical analysis of these results are closely related to physical constitution(height, weight, chest circumference). There have been increasing changes in linear measurement and decreasing changes in breast volume during the last 10 years, The results were as follows: 1) the mean distance from the midclavicular point to the nipple was 19.5cm, the distance from the sternal notch to the nipple was 19.4cm, the distance between nipples was 18.6cm, and the areolar diameter was 3.3cm, 2) the regression equation for the midclavicular point to the nipple was 7.236+ 0.00077x height(cm)+ 0.233 x weight(kg), for the sternal notch to the nipple was 8.845-0.0039 x height(cm)+ 0.214x weight(kg), for the distance between nipples was 11.192 - 0.0033xheight(cm)+ 0.151x weight(kg), and for the areolar diameter was 4.031+0.02xheight(cm)-0.048 x weight(kg),3) the mean value of breast volume of the left side was 209.6cc, and that of the right side was 211.8cc, 4) the regression equation for the mean breast volume was -137.673 + 6.668 x weight(kg), which was equal to -528.414 + 9.115x chest circumference under the axilla(cm) and -468.420 + 8.298 x chest circumference across the nipple (cm). In conclusion, these data could be useful for numerous aspects of breast surgery, including augmentation mammoplasty, mastopexy, reduction mammoplasty, and correction of asymmetrical breasts as the standard for Korean females, if we know the body constituents (weight, chest circumference) before surgery.

Before impression making in the fixed restorations or other prosthesis, hemostatic solutions are used for hemostasis and moisture control. Hemostatic solutions effectively control bleeding but their major ingredients, acid removes smear layers which are formed in the tooth preparation, exposes the dentinal tubular orifices which are occluded by smear layers, makes dentinal tubular fluid displace more easily to the various external stimulus, and according to the hydrodynamic theory, consequently causes dentin hypersensitivity. To know the effect of hemostatic solutions on dentin permeability, coronal dentin discs, 1 mm in thickness, were prepared from extracted third molars free from decay and wear, and a spilt chamber device was used. Hydraulic conductance values and SEMs, which were measured before and after treatment with Astringedentr , Altract and Epri-dent , were compared and analyzed. The following conclusion were drawn : 1. Hydraulic conductance values which wee measured after the treatment of hemostatic solutions were increased in all groups(p<0.05). 2. %change values of hydraulic conductance were compared but no significant difference was found among the three hemostatic solutions(p<0.05). 3. on SEM observations of all groups, after treatment smear layers were removed and dentinal tubular orifices were partially exposed. on the basis of these conclusions, the reckless use of hemostatic solutions should be restricted, and when in use, various methods should be considered to protect dentin.

The authors developed a computer program for use in report printing as well as data storage and retrieval for the gastrointestinal endoscopy service. This program used IBM PC XT and was written in dBASE III plus language. We applied the automatic SNOMED coding method, which is one of the most efficient and accurate method of computerization of medical data. The working sheet which contained the results of previous endoscopic studies could be printed during registration. The dBASE word processor enabled issuing of the formal report of endoscopic result, and the data storage was carried out during the typewriting of the report. Two kinds of data files were stored in the hard disk; the temporary file contained full informations and the permanent file contained patients identification data and SNOMED code. Searching of a specific case was performed by chart number, patients name, date of study, or SNOMED code within a second. All the cases were arranged by SNOMED codes of procedure, topography and morphology codes. Every new data was copied to the diskette automatically. with which data could be restored in case of hard disk failure. The main advantages of this program in comparison to the large main frame computer system are low price, flexibility and easy accessibility. Based on our experience (including surgical pathology department, radiology, clinical pathology), we assume that this program may fit every endoscopy room where there are less than 20,000 cases per year.
