Dissociation of CO from carboxyhemoglobin.
Sharma VS, Schmidt MR, Ranney HM.
The reaction between carboxyhemoglobin and reduced microperoxidase (MP): Hb4(CO)4 + 4MP=Hb4 + 4MPCO, recently reported by us, has been further studied. By generating species Hb4(CO), Hb4(CO)2, and Hb(CO)3 in the stopped flow cuvette by the reaction of dithionite with the species of the general formula Hb4(O2)x(CO)y(x + y=4) in the presence of microperoxidase it has been possible to determine the stepwise CO dissociation rate constants l4, l3, l2, and l1. The overall CO dissociation rate constant l, which is the same in this system as l4, is not affected by 2,3-diphosphoglyceric acid. The activation energy of the reaction is 21,400 cal in 15-25 degrees range. The ratio deltal/deltapH is approximately 3 in 6.5 to 7.5 pH range. The kinetic data indicate that, compared to HbO2, the contribution to the cooperativity of the dissociation rate constants of carboxyhemoglobin is greatly reduced. The ligand-dependent differences in the reactions of Hb with CO, O2, and NO suggest that in the combination reactions the ligand plays an active role in the rate-limiting step.

Acid-base curve nomogram for dog blood.
Emuakpor DS, Maas AH, Ruigrok TJ, Zimmerman AN.
Pooled canine blood of different hemoglobin concentration was equilibrated with two carbon dioxide tensions and the resulting pH's of the samples were measured at 38 degrees C. Readings obtained provided data for the construction of a cartesian nomogram for the dog, based on the pH/log pCO2 coordinate system. The nomogram can be used to evaluate both respiratory and non-respiratory acid-base parameters. For contrast, a control nomogram on human blood was also constructed. Both nomograms show broad similarity. This is to be expected as the normal criteria used to define base excess relating to dog blood are the same as those used for human blood. Nonetheless, base excess and buffer base calculations using the nomogram for the dog and that for man show a deviation of 2.5-10%, and we consider this deviation to be more due to a species difference than to any summated experimental error.

[Examinations to phenomenon of shock-lung (author's transl)]
[Article in German]
Joachim H, Vogel W, Mittermayer C.
The pathogenesis of shock lung as well as the success of therapy in this condition was studied in 79 cases of extrathoracic trauma. The water-, hemoglobin-, and DNA contents of the lungs were measured in order to determine the extent of edema, the rate of perfusion, and proliferation. The cases were divided into two groups according to whether they had or had not received medical therapy before death. The data from these two groups were compared using statistical methods in which time of survival was especially taken into account. The fluid balance, pO2, pCO2, central venous pressure, pH of the serum, total serum protein and serum creatinine were also studied in these cases. Results of the study are as follows. Three phases of the posttraumatic syndrome of shock-lung could be distinguished: phase I (initial phase): blood perfusion is increased, edema is beginning to form, and medical treatment has not yet begun. Phase II (early phase = sydrome of early respiratory failure): pulmonary edema is developing rapidly while perfusion is decreasing. Phase III (late phase = syndrome of late respiratory failure): proliferative changes predominante and the edema is still increasing. The mean weight of the lungs was 397 g (s = 170) in phase I, 774 G (S = 361) In phase II, and 1124 g (s = 310) in phase III. The survival times correlated significantly and positively with the amount of water and DNS in the lungs and significantly and negatively to the amount of hemoglobin in the lungs. Thus, increasing pulmonary edema and increasing proliferative changes occurred with decreasing pulmonary perfusion. This correlation was even noted in groups of patients who had not received medical treatment and whose survival times were short. In treated cases, the fluid balance was significantly and negatively correlated to the total serum protein.

In chronic renal failure high serum urea levels (sUrea) are correlated with the onset of uremic symptoms. Urea has generally been considered relatively non-toxic, functioning more as a surrogate for other toxic solutes; however, it has been recently reported that it can contribute to uremic toxicity. Clinically sUrea are often difficult to interpret because of the wide range of kidney functions. To obtain a practical and easily accessible tool to evaluate sUrea, we have produced percentile curves for different ranges of chronic renal failure, defined with creatinine clearance ( C(Cr)) obtained with the Schwartz formula. Data were obtained from the Italian Pediatric Registry of Chronic Renal Failure (ItalKid); its inclusion criteria are: (1) C(Cr )<75 ml/min per 1.73 m(2), (2) age <20 years at time of registration, and (3) conservative treatment. To obtain the percentiles, the following patients were excluded: patients with an underlying disease, a concomitant treatment, or a disorder that could affect urea metabolism, per se, and/or food intake, and patients aged <2 years. The study group included 690 subjects (mean age 9.56+/-4.54 years, 485 males). In total, 2,085 observations (C(Cr )and sUrea) were available for the construction of the percentile curves. A median of 258 (range 99-380) observations was obtained for each of the eight different categories of C(Cr )(intervals of 10 ml/min per 1.73 m(2)). The 10th, 25th, 50th, 75th, and 90th percentiles were calculated and a graph was produced. Patients with the highest urea percentiles showed significantly higher plasma levels of phosphorus and parathyroid hormone and significantly lower hemoglobin concentrations and bicarbonate levels. Our percentile curves may help to identify subjects with inappropriate sUrea for a given C(Cr).

Analysis of the interaction of organic phosphates with hemoglobin.
Szabo A, Karplus M.
The interaction of organic phosphates with hemoglobin is studied by use of a simple thermodynamic approach. A model-independent analysis is employed to evaluate the accuracy of Adair constants determined in the presence of 2,3-diphosphoglycerate (DPG). The change of oxygen affinity in the presence of phosphates is related to the macroscopic phosphate binding constants of oxy- and deoxyhemoglobin and used to extract such binding constants from oxygen equilibrium measurements. The change of the Bohr effect in the presence of phosphates and the competitive binding of carbon dioxide and DPG are treated quantitatively. The binding of organic phosphates is incorporated into an allosteric model, in which the effect of phosphate on both tertiary and quaternary structure changes is included. By use of this model, the factors which can be responsible for the increased functional heterogeneity of alpha and beta chains in the presence of phosphates are clarified.

Hair loss is a problem in modern soceity. Examining the factors of hair growth may
shed light on how hair loss might occur.
How long can hair grow before it stops growing eventually if it does?
Given that the hair growth rate is quite uniform and constant, somewhere between 0.3-0.5 millimeters per day, it's believed that the length of anagen, the growth phase, differs among individuals, and this is the major determinant to the maximum hair length. For some individuals, anagen may last ten years. Of course the length of the anagen is governed by genes, and the genetic background of the individuals. Non-genetic factors such as nutritional condition, weather, seasonal changes (hair may grow a bit faster during winter), taking medications, health condition may of course influence the rate of
hair growth as well as
hair loss.
The shape of the hair, straight or curly, is dependent on the shape of the follicle. A circular or round hair follicle would generate straight hair, while the follicle with oval or elliptical shapes (in its cross-section) would produce a curly hair.
DHEA is a natural hormone, and it is produced in our body by the adrenal glands.
DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones)
or estrogens (female hormones) in the cells.
