Abstract
Microtubule protein, prepared by cycles of polymerisation and dissociation, contained a nucleoside diphosphokinase (NDP kinase) activity (EC 2.7.4.6). This activity was not intrinsic to the tubulin dimer or the so-called microtubule-associated proteins. The NDP kinase had the following properties. (1) The enzyme existed in a low-molecular-weight form and in association with the complex of microtubule-associated proteins and tubulin (i.e. multimeric tubulin). (2) The low-molecular-weight species was also formed by dissociation of multimeric tubulin by salt or by removal of microtubule-associated proteins on phosphocellulose. (3) GDP bound to the exchangeable site of multimeric tubulin and also GDP derived from the E site of the tubulin dimer was a substrate for the NDP kinase. (4) The NDP kinase showed a 7-fold increase in activity during ATP-dependent microtubule assembly. On the basis of these properties, it is proposed that microtubule protein contains an NDP kinase specifically associated with tubulin and its functions.

Abstract
Subacute intracranial hematomas have variable appearances on high-field MR images. They are hyperintense on T1-weighted images owing to methemoglobin, but have variable intensities on T2-weighted images. Observation of the different high-field spin-echo MR intensity patterns of five subacute hematomas suggests that further subcategorization into different methemoglobin states may be possible. In particular, undiluted intracellular methemoglobin is hyperintense on T1-weighted images and markedly hypointense on T2-weighted images, undiluted free methemoglobin should be hyperintense on T1-weighted images and isointense or slightly hypointense on T2-weighted images, and dilute free methemoglobin is hyperintense on both T1- and T2-weighted images. However, it appears that certain regions of subacute hematomas may be difficult to differentiate, by intensity patterns alone, from melanotic melanomas or fat. We believe that, despite some limitations, MR is useful in dividing subacute intracranial hematomas into their respective methemoglobin states, and also that further subcategorization is possible.

Abstract
An auxin binding sive, with characteristics different from the previously described auxin binding sites I and II in maize coleoptiles, is reported in homogenates of zucchini (Cucurbita pepo L. cv. Black Beauty) hypocotyls. Evidence from differential centrifugation and sucrose and metrizamide density gradients indicates that the site is localized on the plasma membrane. The site has a KD of 1-2×10(-6) M for indole acetic acid and has a pH optimum of 5.0. Binding specificity measured with several auxins, weak auxins, and anti-auxins generally parallels the activities of the same compounds as inhibitors of auxin transport. 1-N-naphthylphthalamic acid and 2,3,5-triiodobenzoic acid (2,3,5-TIBA), both auxin transport inhibitors in vivo, increase specific auxin binding to this site. 3,4,5-TIBA, which can partially reverse 2,3,5-TIBA's transport inhibition when the two substances are added together in vivo, partially reverses 2,3,5-TIBA's increase in specific auxin binding to the plasma membrane site when added with 2,3,5-TIBA in vitro. Preliminary investigations indicate that a similar plasma membrane site exists in maize (Zea mays L.) coleoptiles. It is suggested that different conformations of this site may function during active auxin transport.

Abstract
The authors reviewed 181 patients who received local radiation therapy for the prevention or control of extramedullary disease resulting from acute leukemia. 126 had acute lymphocytic leukemia and 55 had acute granulocytic leukemia. They were treated over a 18-year period of time with different forms of chemotherapy. Most had not received prophylactic CNS radiation therapy. Patients were evaluated for local control until death or hematologic relapse intervened. More than 80% of patients with clinical ALL meningeal leukemia had a successful response to doses over 1000 rads. This same response was not apparent in AML. More than 80% of clinical non-CNS extra medullary leukemia was controlled with doses of 600 rads or greater. Only one patient with extra-medullary relapse is still alive. The authors feel that lower preventative doses of radiation to the CNS are compatible with similar control rates, based on their own data and other suggestive data.

Abstract
Ninety-six pre- and postanastomosis allograft biopsies from 48 transplant recipients were studied employing the direct fluorescent antibody procedure. Of the 48 transplants studied, 26 postanastomosis biopsies showed significant blood vessel wall deposits consisting predominantly of 2-4+ staining IgM and C3 deposits. The corresponding preanastomosis biopsies showed only patchy intimal surface staining. All but two of the grafts with positive biopsies had been preserved by the pulsatile perfusion method for various periods of time. Twenty-three of the twenty-six grafts with positive findings failed within 1 month while only 2 of the 19 negative postanastomosis biopsies failed within the 1-month period. Based on these findings actual graft failure occurred in 89% of the patients with postanastomosis transplant biopsies with positive findings. Although crossmatch studies were negative in all cases, further immunologic studies of eluates obtained from positive postanastomosis biopsies revealed the presence of lymphocytotoxic IgM antibodies in three of five cases studied. These findings suggest that rapid deposition of undetected preformed lymphocytotoxic antibodies accumulate in the vessel walls following anastomosis and contribute to transplant failure.

Abstract
A pH microelectrode has been used to investigate the auxin effect on free space pH and its correlation with auxin-stimulated elongation in segments of pea (Pisum sativum) stem and maize (Zea mays var. Bear Hybrid) coleoptile tissue. Auxin induces a decrease in free space pH in both tissues. In maize coleoptiles, free space pH begins to fall within about 12 minutes of exposure to auxin and decreases by about 1 pH unit by approximately 30 minutes. In pea, pH begins to decrease within an average of 15 to 18 minutes of exposure to auxin and falls by about 0.9 pH unit by approximately 40 minutes. Auxin-stimulated elongation, measured in the same two tissues similarly prepared, appears in maize at the earliest 18 minutes after auxin application, while in pea it appears at the earliest 21 to 24 minutes after auxin application. The auxin analogs p-chlorophenoxyisobutyric acid and phenylacetic acid do not stimulate elongation above control levels in maize or pea tissue segments and do not cause a decrease in free space pH in either tissue. These findings are consistent with the acid secretion theory of auxin action.

Abstract
The decision on whether industrial waste should be deposited on general or special dumps depends upon the toxicity of the waste and thus upon the risk of ground-water pollution and the killing off of micro-organisms responsible for breaking down waste products. Since chemical analyses that are to provide information on toxicity are frequently very costly, an attempt was made to determine the toxicity of solid or semi-solid waste with the aid of a bacterial test. As in the perforated-plate test, here, too, the formation and size of inhibition zones were used to determine the toxicity after diffusion of substances contained in industrial waste. About 30 different types of industrial waste were examined with this method. For almost all substances a positive correlation of the (known) constituents of waste to the formation of inhibition zones was found to exist. The influence exercised by solubility and diffusibility and other problems are dealt with.

Abstract
The clinical course of 130 patients treated for malignant parotid tumors at the three institutions have been reviewed. Fifty-six of these 130 patients developed recurrences following their primary treatment by a surgical procedure. There were a total of 109 recurrences among these 56 patients. The average number of recurrences was two per patient. The average survival from first recurrence was 3.7 years, with the median survival 2 years. The range of survival was 0.5 to 17 years. Once recurrence developed, treatment was by surgery, radiation therapy, chemotherapy, or a combination. Of 56 patients with recurrence, 33 are dead and 9 patients are alive with disease. Fourteen patients are alive and well with no evidence of disease. These NED patients had an average number of 1.6 recurrences and a median survival to date of only 3 years. Our study indicates that for the majority of patients who develop recurrence, survival is relatively short and treatment is usually ineffective in three of four patients. The authors conclude that after a surgical procedure for malignant salivary gland tumors, a trial of wide field postoperative radiation therapy to high dose should be considered as part of the initial treatment.
