36 test anxious Ss were randomly assigned to 3 groups. One group served as the no-treatment control, while the other two groups received either placebo-attention or implosive therapy. Implosive therapy consisted of 5 30-min. sessions of treatment in which Ss were asked to imagine highly anxiety-evoking scenes pertaining to test anxiety while concentrating on experiencing the accompanying sensations as intensely as possible. The placebo group imagined non-relevant scenes while concentrating on experiencing the accompanying sensations as intensely as possible. The results indicated a significant difference in terms of anxiety reduction between the no-treatment control group and the implosive-therapy group. No significant difference was obtained between the placebo group and the implosive-therapy group, or between the placebo group and the no-treatment group. The importance of a placebo group in behavior therapy research was noted.

In an attempt to help underachieving students improve academic performance, an Achievement Motivation Training program was developed. Although similar to other programs focusing on achievement motivation, substantial differences exist, particularly since the present program is presented in an outpatient format rather than integrated into the classroom. 54 students (Grades 3 to 11), referred by their counselors, were subjects; half of these completed our Achievement Motivation Training program, the other half served as a no-treatment control group. The treated group showed a significant improvement in grades from before training to follow-up as well as significantly greater improvement than the control group. Also, a new methodology was offered and tested, demonstrating that a no-treatment group may not be necessary when grades are the primary dependent variable.

The value of melengestrol acetate (MGA) as a means of suppressing oestrus and its administration by utilising the licking behaviour of the animal were investigated in 3 groups of 30 Sahiwal cross heifers. For 63 days 0.5 mg MGA was either individually fed daily (fed group) or applied daily with molasses to the midrib of heifers to be licked off (licking group). The third group received no treatment (control group). When treatments ceased, fertile bulls were introduced for 11 weeks. The heifers were then slaughtered. Control animals exhibited oestrus regularly throughout the treatment period while those in the treated groups failed to exhibit oestrus after the first week. Post treatment oestrus was synchronised in the fed group but only partial synchronisation occurred in the licking group. Pregnancy rates from the first post-treatment oestrus of 63, 17 and 33% for the control, fed and licking groups respectively were significantly different (P<0.01). Pregnancy rates of 87, 60 and 80% from the first plus second post-treatment oestrus for the control, fed and licking groups respectively also differed significantly (P<0.05). There was no significant difference in the cumulative pregnancy rates after the third post-treatment oestrus. This study demonstrated that daily oral administration of MGA suppresses oestrus in heifers, but pregnancy rates following cessation of treatment are depressed. Application of MGA with molasses to an area on the coat to exploit the licking behaviour of the animal appeared successful. However, the practicability of the technique needs verification under extensive grazing conditions.

The purpose of this study was to evaluate the efficacy of alveolar corticotomy on orthodontic tooth movement when retracting upper canines compared with the conventionnal treatment. The sample consisted of 30 patients with a mean age of 21 ± 2 years requiring the therapeutic extraction of the maxillary first premolars, with subsequent retraction of the maxillary canines. The subjects were divided into two groups, one receiving orthodontic treatment assisted corticotomy (experimental group) and the other conventional treatment (control group). The velocity of the retraction of the upper canine was evaluated by measuring the distance between the canine and second premolar on each side of the mouth for both groups at 2 months, and 4 months after canine retraction. Results: the velocity of canine was significantly higher on the experimental group than the control group by two times during the first two months after canine retraction. This rate declined to 1.25 times higher after four months. Conclusion: alveolar corticotomy increased orthodontic tooth movement when retracting upper canines.

30 test-anxious nursing students were randomly assigned to either a massed desensitization, placebo, or control group. All treatment was applied in 3 2-hr. and 20-min. sessions over an 8-day period. The massed group desensitization sessions began with 20 min. of recorded relaxation instructions. The remainder of the sessions consisted of Ss visualizing items from a test-anxiety hierarchy while concentrating on remaining relaxed. The placebo group sessions began with 20 min. of a recorded presentation on the merits of good study techniques, concentration, learning, and personal efficiency. Lectures on these topics comprised the remainder of the sessions. The control Ss merely received the pre- and post-treatment measures. A significant difference ( p.01) was obtained on the posttest measure between the massed desensitization group and the placebo group and between the massed desensitization and control groups. The results of this study agree with earlier studies which indicate that massed group desensitization is an efficient and efficacious procedure for the reduction of anxiety based disorders.

ABSTRACT The mode of action of a single injection of testosterone propionate on LH secretion and release has been studied in the castrated ram. In the first experiment, six castrated rams were injected intramuscularly with 400 mg of testosterone propionate, and the plasma LH levels were assayed by radioimmunoassay: on the first day after treatment, the plasma LH levels decreased significantly (P < 0.001), then remained at a very low level for 5–7 days; initial LH levels were restored by day 9. Testosterone propionate thus blocks the discharge of LH. A second experiment was then performed. Castrated rams in groups of 3 were killed either without treatment (control group D0), or 2, 7 or 9 days after the injection of testosterone propionate (groups D2, D7 and D9). In addition to the plasma LH, hypophyseal LH and hypothalamus LRF (LH releasing factor) were measured: the LRF activity was assessed by the quantity of LH released in vitro from the hypophysis of castrated rats blocked with testosterone propionate. The LH released into the incubation medium and the hypophyseal LH of the ram were measured by the ovarian ascorbic acid method and by radioimmunology. The results of the plasma LH assays were comparable to those in the first experiment: plasma LH was significantly decreased in group D2, increased in group D7 and was restored in group D9. Hypophyseal levels, on the other hand, increased in groups D2 and D7, but were comparable to the controls in group D9, indicating that the injection of testosterone propionate had little or no effect on LH secretion. Finally, the LRF activity was considerably reduced in group D2 (P<0.001) as compared with the controls (D0), but similar to the control values in group D9. Although secretion appeared normal, the decreased plasma LH levels in group D2 indicated that LRF had not been released; consequently the decrease in LRF observed can be interpreted as being due to an inhibition of its synthesis under the influence of testosterone propionate.

Purpose: To evaluate and compare corneal hysteresis (CH), corneal resistance factor (CRF), and central corneal thickness (CCT), measurements were taken between a healthy population (controls), patients diagnosed with glaucoma (DG), and glaucoma suspect patients due to ocular hypertension (OHT), family history of glaucoma (FHG), or glaucoma-like optic discs (GLD). Additionally, Goldmann-correlated intraocular pressure (IOPg) and corneal-compensated IOP (IOPcc) were compared between the different groups of patients. Methods: In this prospective analytical-observational study, a total of 1065 patients (one eye of each) were recruited to undergo Ocular Response Analyzer (ORA) testing, ultrasound pachymetry, and clinical examination. Corneal biomechanical parameters (CH, CRF), CCT, IOPg, and IOPcc were measured in the control group (n = 574) and the other groups: DG (n = 147), FHG (n = 78), GLD (n = 90), and OHT (n = 176). We performed a variance analysis (ANOVA) for all the dependent variables according to the different diagnostic categories with multiple comparisons to identify the differences between the diagnostic categories, deeming p < 0.05 as statistically significant. Results: The mean CH in the DG group (9.69 mmHg) was significantly lower compared to controls (10.75 mmHg; mean difference 1.05, p < 0.001), FHG (10.70 mmHg; mean difference 1.00, p < 0.05), GLD (10.63 mmHg; mean difference 0.93, p < 0.05) and OHT (10.54 mmHg; mean difference 0.84, p < 0.05). No glaucoma suspects (FHG, GLD, OHT groups) presented significant differences between themselves and the control group (p = 1.00). No statistically significant differences were found in the mean CRF between DG (11.18 mmHg) and the control group (10.75 mmHg; mean difference 0.42, p = 0.40). The FHG and OHT groups showed significantly higher mean CRF values (12.32 and 12.41 mmHg, respectively) than the DG group (11.18 mmHg), with mean differences of 1.13 (p < 0.05) and 1.22 (p < 0.001), respectively. No statistically significant differences were found in CCT in the analysis between DG (562 μ) and the other groups (control = 556 μ, FHG = 576 μ, GLD = 569 μ, OHT = 570 μ). The means of IOPg and IOPcc values were higher in the DG patient and suspect groups than in the control group, with statistically significant differences in all groups (p < 0.001). Conclusion: This study presents corneal biomechanical values (CH, CRF), CCT, IOPg, and IOPcc for diagnosed glaucoma patients, three suspected glaucoma groups, and a healthy population, using the ORA. Mean CH values were markedly lower in the DG group (diagnosed with glaucoma damage) compared to the other groups. No significant difference was found in CCT between the DG and control groups. Unexpectedly, CRF showed higher values in all groups than in the control group, but the difference was only statistically significant in the suspect groups (FHG, GLD, and OHT), not in the DG group.

In the porcine coronary artery, regenerated endothelium is dysfunctional as regards the responses to endothelium-dependent agonists. The current study aimed to determine the possible involvement of histamine in such dysfunction. Pigs were treated chronically with pyrilamine (H1 receptor inhibitor, 2 mg·kg−1·day−1) with part of their coronary endothelium and allowed to regenerate for 28 days after balloon denudation. The results showed a reduction in relaxation to bradykinin (Gq protein dependent) only in the pyrilamine-treated group (area under the curve, 269.7 ± 13.4 vs. 142.0 ± 31.0, native endothelium vs. regenerated endothelium) but not in the control group (253.0 ± 22.1 vs. 231.9 ± 29.5, native endothelium vs. regenerated endothelium). The differences in the relaxation to serotonin (Gi protein dependent) between native and regenerated endothelium were not affected by the pyrilamine treatment (control group, 106.3 ± 17.0 vs. 55.61 ± 12.7; and pyrilamine group, 106.0 ± 8.20 vs. 49.30 ± 6.31, native endothelium vs. regenerated endothelium). These findings indicate that during regeneration of the endothelium, the activation of H1 receptors by endogenous histamine may be required to maintain the endothelium-dependent Gq protein-mediated relaxation to bradykinin, suggesting a beneficial role of the monoamine in the process of endothelial regeneration.

The purpose of this study was to evaluate the effects of aroma massage applied to middle-aged women with hypertension. The research study had a nonequivalent control group, nonsynchronized design to investigate the effect on home blood pressure (BP), ambulatory BP, and sleep. The hypertensive patients were allocated into the aroma massage group (n=28), the placebo group (n=28), and the no-treatment control group (n=27). To evaluate the effects of aroma massage, the experimental group received a massage with essential oils prescribed by an aromatherapist once a week and body cream once a day. The placebo group received a massage using artificial fragrance oil once a week and body cream once a day. BP, pulse rate, sleep conditions, and 24-hour ambulatory BP were monitored before and after the experiment. There was a significant difference in home systolic blood pressure (SBP) (F=6.71,P=0.002) between groups after intervention. There was also a significant difference in SBP (F=13.34,P=0.001) and diastolic blood pressure (DBP) (F=8.46,P=0.005) in the laboratory between aroma massage and placebo groups. In sleep quality, there was a significant difference between groups (F=6.75,P=0.002). In conclusion, aroma massage may help improve patient quality of life and maintain health as a nursing intervention in daily life.

Integrating the properties of computer algebra systems and dynamic geometry environments, Geogebra became an effective and powerful tool for teaching and learning mathematics. One of the reasons that teachers use Geogebra in mathematics classrooms is to make students learn mathematics meaningfully and conceptually. From this perspective, the purpose of this study was to investigate whether instruction with Geogebra has effect on students’ achievements regarding their conceptual and procedural knowledge on the applications of derivative subject. This study adopted the quantitative approach with pre-test post-test control group true experimental design. The participants were composed of two calculus classrooms involving 31 and 24 students, respectively. The experimental group with 31 students received instruction with Geogebra while the control group received traditional instruction in learning the applications of derivative. Independent samples t-test was used in the analysis of the data gathered from students’ responses to Applications of Derivative Test which was subjected to them before and after teaching processes. The findings indicated that instruction with Geogebra had positive effect on students’ scores regarding conceptual knowledge and their overall scores. On the other hand, there was no significant difference between experimental and control group students’ scores regarding procedural knowledge. It could be concluded that students in both groups were focused on procedural knowledge to be successful in learning calculus subjects including applications of derivative in both groups. On the other hand, instruction with Geogebra supported students’ learning these subjects meaningfully and conceptually.
