And Control

One hundred normal subjects, divided into five groups, read aloud for 40 minutes. For the first 10 minutes (Baserate), subjects read without interruption. For the next 20 minutes (Conditioning), verbal stimuli contingent upon disfluency were delivered to three groups. One group received “wrong”; the second, “no”; and the third “huh-uh” for disfluency. A fourth group received “wrong” on a random schedule during Conditioning, while the fifth (control) received no verbal stimuli. During the last 10 minutes (Extinction), no verbal stimuli were delivered to any group. Random and Control subjects did not change disfluency rates, while subjects in all contingent conditions decreased disfluency in Conditioning. Contingent “wrong” produced the greatest decrement in disfluency, “no” the least, and “huh-uh” occupied a midpoint.

Cataract Patients

1. Cataract is the single major cause of blindness worldwide; however, the reasons for the development of this condition remain unknown. It has been suggested that the essential amino acid tryptophan may be implicated in the aetiology but definitive evidence has been lacking. 2. The serum levels of tryptophan and seven of its metabolites have been measured in both cataract patients and control subjects, after administration of tryptophan, in order to determine the typical response profile and to discover whether differences could be found in tryptophan metabolism in the two groups. 3. Tryptophan, kynurenine, kynurenic acid, xanthurenic acid, 3-hydroxyanthranilic acid, 5-hydroxyanthranilic acid, 5-hydroxytryptophan and anthranilic acid were measured by HPLC with dual electrochemical and programmable wavelength fluorescence detection. Fasting cataract patients (n = 42) and control subjects (n = 37) were given an oral dose of l-tryptophan and sera were sampled at 0, 1, 2, 4 and 6 h. 4. Statistically significant differences in the distribution of data between the two groups were observed. The responses of kynurenine and 5-hydroxyanthranilic acid were higher in cataract patients, but those of kynurenic acid and total tryptophan were lower than in control subjects. No statistically significant differences in free tryptophan, anthranilic acid, 3-hydroxyanthranilic acid, xanthurenic acid or 5-hydroxytryptophan levels were noted. 5. We conclude that there is a major subgroup of age-related cataract patients with a dysfunction in the metabolism of tryptophan. This may be related to the onset of cataract. The mechanism remains to be established but may operate via the action of tryptophan metabolites, such as 5-hydroxyanthranilic acid, which become reactive towards protein upon oxidation.

And Control

Patients with open bite often show a weak occlusal force and temporomandibular disorders (TMDs). If these are the main cause of open bite, it may be hypothesized that both pre-pubertal and adult open-bite patients would show a weak occlusal force and abnormal condylar motion. The purpose of this study was to test this hypothesis. Test group subjects consisted of 13 consecutive pre-pubertal and 13 adult patients with anterior open bite. They were compared with age-matched normal subjects. The adult open-bite group showed a weaker occlusal force and a shorter range of condylar motion compared with the control subjects. In the pre-pubertal subjects, however, there were no significant differences in the occlusal force and range of condylar motion between the open-bite and control groups. Therefore, these results suggest that a weak occlusal force or TMDs may not be the main cause of open bite.

1. Exchange of metabolic substrates was studied across the leg at rest and during a bicycle exercise demanding 50% of the maximal oxygen uptake in seven patients with juvenile diabetes and six control subjects. The leg blood flow and the femoral arterial and venous substrate concentrations were measured in the fasting state and, in the diabetic subjects, 24 h after the last administration of insulin. 2. At rest a close correlation was seen in the control subjects between the leg glucose uptake and the arterial insulin concentration. The diabetic subjects, including three patients in whom it could be shown that the insulin concentrations were extremely low, had a resting glucose uptake in the same order of magnitude as the control subjects. The glucose uptake was inversely related to the arterial concentrations of non-esterified fatty acids in both groups. 3. During exercise the glucose uptake increased in both patients and control subjects, but the increase was not related to arterial concentrations of insulin or non-esterified fatty acids. 4. The release of lactate, pyruvate, alanine and glycerol from the leg was not different in diabetic and control subjects neither at rest nor during exercise. 5. The ketonaemia was increased in the diabetic subjects, but the uptake of total ketone bodies was not different in the two groups. No increase in the uptake of total ketone bodies in control and diabetic subjects was found during exercise. The leg uptake of acetoacetate was a function of the substrate load and tended to be higher in diabetic subjects during exercise, when no net uptake of β-hydroxybutyrate was found. 6. The above results suggest that the glucose uptake in human skeletal muscle at rest depends on the concentration of insulin and possibly also of non-esterified fatty acids in arterial blood. In contrast the glucose uptake during exercise is not related to the concentration of insulin or non-esterified fatty acids, which may explain why no differences in this aspect are seen between the leg metabolism of diabetic and normal subjects.

Neurolinguistic programming's hypothesized eye movements were measured independently using videotapes of 10 nonfluent aphasic and 10 control subjects matched for age and sex. Chi-squared analysis indicated that eye-position responses were significantly different for the groups. Although earlier research has not supported the hypothesized eye positions for normal subjects, the present findings support the contention that eye-position responses may differ between neurologically normal and aphasic individuals.

1. Erythrocyte choline transport was studied in 10 haemodialysis patients immediately before and after a haemodialysis session and in 10 control subjects. Choline uptake was measured in erythrocytes from normal and uraemic patients after washing in vitro and subsequent incubation in autologous plasma. Amines present in uraemic plasma were examined for their effect on choline transport in normal erythrocytes. 2. NMR spectroscopy was used to measure choline, trimethylamine and dimethylamine in erythrocyte extracts from nine control subjects, 32 subjects with renal impairment and nine samples from haemodialysis patients. 3. The increased choline influx in uraemic erythrocytes is significantly decreased by prior haemodialysis (mean Vmax pre-dialysis 146±20 μmol h−1 I−1, postdialysis 113±13 μ/mol h–1 I−1 (P < 0.005). After in vitro washing there is a fall in Vmax, and no longer any significant difference between pre- and post-dialysis samples. There remains a significant difference in the erythrocyte choline Vmax between samples from patients with chronic renal failure and from normal subjects (P < 0.005). 4. Human plasma was found to contain factors capable of increasing choline uptake. Trimethylamine and dimethylamine were found to inhibit choline uptake. Trimethylamine and trimethylamine-N-oxide transstimulated choline efflux, but the major transport substrate present in erythrocyte extracts from all groups was choline, which was higher in those with renal impairment (71 ± 10 μmol/l) than in haemodialysis patients (47 ± 10 μmol/l) and control subjects with normal renal function (40 ± 9 μmol/l). 5. Our data suggest that erythrocyte choline transport is increased in uraemia as a consequence of increased transporter number or activity, rather than the presence of intracellular substrate.

1. Methylcobalamin (Me-B12), adenosylcobalamin (Ado-B12), hydroxocobalamin (OH-B12) and cyanocobalamin (CN-B12) have been estimated by a chromatographic—bioautographic technique in plasma, erythrocytes, leucocytes and bone marrow from normal subjects, hospital controls and patients with untreated pernicious anaemia. 2. Estimates of concentrations of cobalamins have also been obtained in bile, cerebrospinal fluid, liver biopsies and in autopsy samples of liver, kidney, spleen, brain and pituitary. 3. In normal and control subjects, Ado-B12 predominated in all samples except plasma, in which Me-B12 was the predominant form. Me-B12, Ado-B12, OH-B12 and CN-B12 were found in normal erythrocytes, leucocytes and bone marrow and the proportion of each cobalamin was fairly similar in all these tissues. In liver, kidney, spleen, brain and pituitary, the proportions of the cobalamins were more variable. No CN-B12 was detected in these organs. 4. In untreated pernicious anaemia, Me-B12 was disproportionately reduced in plasma, but not in erythrocytes, leucocytes or bone marrow. There was a small increase in the proportion of CN-B12 in plasma, blood cells and bone marrow in untreated pernicious anaemia.

Speaking Task

Seventy-two college students were divided into three groups: Button Push-Speech (BP-S), Speech-Button Push (S-BP), and Control. BP-S subjects pushed one of two buttons on signal for 8 min. During the last 4 min, depression of the criterion button caused a buzzer to sound. After the button-push task, subjects spoke spontaneously for 30 min. During the last 20 min, the buzzer was presented contingent upon each disfluency. S-BP subjects were run under the same procedures, but the order of button-push and speech tasks was reversed. Control subjects followed the same procedures as S-BP subjects, but no buzzer signal was presented at any time. Both S-BP and BP-S subjects emitted significantly fewer disfluencies during the last 20 min (Conditioning) than during the first 10 min (Baserate) of the speaking task. The frequency of disfluencies for Control subjects did not change significantly from Baserate to Conditioning. In none of the three groups did the frequency of pushes on the criterion button change significantly from minute to minute throughout the 8-min button-push session.

SummaryPlatelets tests, acute phase reactants and serum lipids were measured in patients with diabetes mellitus and patients with peripheral vascular disease. Patients frequently had abnormal platelet tests and significantly increased acute phase reactants and serum lipids, compared to young healthy control subjects. These differences were compared with multidiscriminant analysis. Patients could be separated in part from the control subjects with variables derived from the measurement of acute phase proteins and serum lipids. Platelet test results improved the separation between diabetics and control subjects, but not between patients with peripheral vascular disease and control subjects. Diabetic patients with severe retinopathy frequently had evidence of platelet activation. They also had increased acute phase reactants and serum lipids compared to diabetics with absent or nonproliferative retinopathy. In patients with peripheral vascular disease, only the fibrinogen concentration was related to the degree of vessel damage by arteriography.

This study was conducted as an attempt to discover the effect of applying Demonstration Method on students’ achievement in speaking skill. It was an experimental research. The subject was students of Grade XII, Vocational High School (Sekolah Menengah Kejuruan: SMK), which consisted of 79 students. The research was divided into two groups: experimental and control groups. The instrument used to collect the data was speaking test. To obtain the reliability of the test, the writer applied Kuder Richardson 21 formula. The result of the reliability was 0.7, and it was found that the test was reliable. The data were analyzed by using t-test formula. The analysis showed that the scores of the students in the experimental group were significantly higher than the scores of the students in the control group at the level of significant m = 0.05 with the degree of freedom (df) 77, t-observed value 8.9 > t-table value 1.99. The findings indicate that using Demonstration Method significantly affected the students’ achievement in speaking skill. So, English teachers are suggested to use Demonstration Method in order to improve students’ achievement in speaking skill.
