In an effort to understand the genetic regulation of membrane morphogenesis, twenty-nine temperature-sensitive mutants of the membrane-containing bacteriophage PM2 were isolated. Characterization at restrictive temperature revealed groups showing no lysis (Groups I--IV), partial lysis (Groups V--VIII), and full lysis (groups IX--XII) of the host Pseudomonas BAL-31. When the cell lysis data are considered in conjunction with data on stimulation of viral DNA synthesis, at least six mutant groups are defined. Analysis by gel electrophoresis of the pattern of viral proteins synthesized under restrictive conditions further divides the mutants into twelve groups. Temperature shift experiments delineate early, intermediate and late mutants. Complementation data support some of these groupings. The observed low levels of complementation and recombination are discussed in terms of gene product/genome restriction, bound to the membrane at the site of infection. It is of particular interest to membrane morphogenesis that under restrictive conditions late mutants in Groups II, III and IV make empty-appearing vesicles inside the cell that are the size of virus membranes as seen in thin sections of cells in the electron microscope. Mutants ts 1 (Group II) and ts 12 (Group III) show defects in their ability to incorporate into membranes viral structural proteins sp 13 and sp 6.6. The possibility is discussed that either of these proteins control the size and shape of the viral membrane.

In the alcohol test for drunken criminals, we introduced Bender-Gestalt test and Rorschach test for the assessment, and examined their usefulness for the evaluation of intoxication patterns according to Binder's classification. The subjects were 24 drunken criminals who were examined by Mental Hygiene Group, Tsukuba University, for psychiatric evidences. The subjects were divided into the ordinary intoxication group (OI group) and the complicated intoxication group (CI group) on the basis of the behavioral assessment, and the psychological tests were performed before and after drinking. The following results were obtained. 1) Alcohol intoxication induced decrease in R1T, W and VIII + IX + X/R and increase of BGT scores and P%, which indicates that subjects become unable to make comprehensive and delicate responses to the external stimuli. 2) When we classified subjects into increasing and decreasing type on the pattern of changes in the BGT score from before to immediately after drinking in each subject, we found the ratio of increasing type in complicated intoxication is more than in ordinary intoxication significantly. And we found significant group x drinking interaction in F+% and At% of Rorschach test. The F+% significantly decreased only in CI group. The At% in CI group tended upward, but downward in OI group. These findings indicated that complicated intoxication reduced the subject's reality testing, while not in ordinary intoxication. 3) Comparing the effects of personality and intoxication factors in complicated intoxication, intoxication factors were considered to play primary roles. 4) We found association between high BAL and reduction of ego function and imagination, which is represented as significant peak of BALx drinking interaction in the BGT scores, M and FM + m. These observations suggest that the psychological tests as part of the alcohol tests are useful for the evaluation and research of intoxication.

Reaction conditions for a variety of endonucleases are detailed in this unit along with discussions of potential applications. Enzymes covered include BAL 31 nuclease, S1 nuclease, mung bean nuclease, micrococcal nuclease, and DNase I. A general discussion regarding the use of endonucleases to generate nonspecific breaks in dsDNA is also provided. For a detailed discussion of the endonucleases more typically associated with DNA damage repair (e.g., Endo III, IV, V and VIII of E. coli and human APE1), see UNIT 3.9.
