The introduction of local anaesthesia in Australia, January 19, 1885.

Medical journals in Australia between 1856 and 1884 were wont to publish many references to forms of local anaesthesia, probably because this form of pain relief was of assistance to lone practitioners in isolated country towns. Some of these methods are described, as is the first use of cocaine by A. S. Gray and J. T. Rudall on January 19, 1885. As in journals elsewhere there followed a spate of articles reporting various aspects of cocaine and its usage, including an abortive attempt to find an alternative agent.

Normal EEG of the restrained twenty-four-hour-old Japanese quail (Coturnix coturnix japonica).

A new method for obtaining bipolar electroencephalographic (EEG) recordings from day-old Japanese quail (Coturnix coturnix japonica) is described. The electrodes are chronically placed stainless steel suture wires sewn into the skull and secured with dental acrylic. Using this arrangement, recordings were made over the hyperstriatum accessorum and dorsoarchistriatum regions of the brain. These records showed a preponderance of high amplitude slow waves. Transitions to low amplitude fast waves were also evident, and rare instances of paradoxical sleep were noted. computerized frequency analyses of the recordings divided wave numbers into distinct groups over the 1 to 17 Hz range: 1 to 4 Hz, 4 to 8 Hz, 8 to 13 Hz, and 13 to 17 Hz. Frequencies of waves detectable across the hyperstriatum accessorum were primarily confined to the 1 to 7 Hz range, whereas waves generated around the dorsoarchistriatus showed more abundant high frequency patterns. Mean amplitude of the waves (10 to 50 muV) showed an inverse exponential relationship with frequency. The method described produced an EEG of good quality on unanesthetized birds with the electrode placement procedures requiring less than 30 min.

Development and evaluation of social skills training for schizophrenic patients in remission.

Investigated were measures of self-esteem, self-perceived attitudinal dimensions and locus of control to assess the effects of group social skills training for schizophrenic psychiatric inpatients. A pretest, posttest control group design was employed utilizing forty subjects currently in treatment. It was hypothesized that short-term cognitively structured group therapy would realize significant improvement in self-esteem, internal locus of control and assertive attitude change. Significant mean differences between the treatment group's level of self-esteem, perceived assertive behavior and internal locus of control as a result of treatment were realized. Discussion of training methodology, issues and import for clinical applications and research are discussed.

Binary assessment of early approach-behaviour in the Japanese quail.

Visually-elicited early approach-behaviour was studied in 1013 Japanese quail chicks (Coturnix coturnix japonica) by a newly developed, binary assessment procedure. This procedure was shown to be highly effective for identifying approach preferences and related indivisual differences in early approach-behaviour. Experimental results show that quail chicks exhibit approach-responses to a flashing light. Within various paired intensity-combinations of the tested intensity-range of approximately two log units, they consistently preferred the higher intensity stimulus.
