Intraaticular treatment of tarsal degenerative joint disease in cattle.
Tarsal degenerative joint disease (DJD) in 12 cattle was classified as primary or secondary, based on age, evidence of hereditary or congenital joint conformation defects, faulty hindlimb alignment, duration and type of usage joints were subjected to, and history or signs of repeated trauma. Three of the cattle had bilateral primary tarsal DJD, 7 had bilateral secondary tarsal DJD, and 2 had secondary DJD of the left tarsus. Analyses of synovial fluid samples provided a means of characterizing pathologic changes of tarsal DJD, Results of blood and synovial fluid analyses were grouped in compilation of data for cattle affected with either primary or secondary tarsal DJD. Corticosteroids and a long-acting synthetic progestational agent were injected singly or in combination with aqueous antibiotics into affected tarsal joints. Tarsal joints of 5 of the cattle responded favorably to a single intraarticular treatment, as manifested by palliative relief and functionally usable joints. Seven joints of 5 cattle were subjected to repeated intraarticular treatment. Serial synovial fluid analyses in 7 of the cattle provided a means of assessing tarsal joint response to intraarticular treatment or to therapeutic arthrocentesis, exclusive of patient objective response. One cow developed a mild self-limiting bilateral postinjection synovitis that was resolved after the 2nd and final intraarticular injection. Usable function returned to tarsal joints of cattle that responded favorably to intraarticular treatment at different periods after single or repeated injections. Three cattle with advanced tarsal DJD experienced minor temporary relief and were euthanatized at their owner's request. Improvement did not occur in the tarsal joint of 1 cow subjected to therapeutic aspiration only. Intraarticular treatment in all cattle was considered supportive to the animal's well-being rather than curative.
[Treatment of advanced neoplasms in the jaw].
Report is made about the combined therapy with cytostatics (methotrexate - bleomycin) and irradiation in patients with extended tumors in the gnathic region. Ten patients in whom a radical therapy with conventional methods did not promise any success, were treated with intra-arterial infusions of methotrexate and bleomycin and simultaneous irradiation. At present, eight patients are tumor free (observation time 4-14 months after termination of therapy). Although radiation doses and doses of cytostatics were high, only insignificant side effects were stated; consequently, the treatment had to be terminated in none of the patients.

Arterial infusion chemotherapy for palliation in far-advanced malignant neoplasms.
For patients with far-advanced regionally localized malignancies, arterial infusion chemotherapy offers reasonable palliation with minimal complications. High locoregional concentration of the antineoplastic drugs is obtained with relatively little systemic toxicity.

[Palliative treatment of liver neoplasms I: localized infusion of antimitotics: premises, technical procedure and limitations].
A hepatic localised antiblastic chemotherapic technique combining limited discomfort for patients with appreciable palliative results is illustrated; a short description of the surgical procedure of intubation of the hepatic artery itself and of some auxiliary procedures is given. Lastly the possible complications and the results are illustrated.
[Palliative treatment of liver neoplasms II: dearterialization of the liver: indications, premises, technic and limitations].
Hepatic arterial vascularisation, as described by Michels in 1954, is outlined; the importance of selective angiography in preparation of the hepatic de-arterialisation operation is then stressed, and its theoretical foundations and the surgical technique are illustrated; other procedures which can usefully be combined are also indicated. Lastly an evaluation of the limits and results of this therapy is given.

Combined therapy with bleomycin and selective intra-arterial infusion of mitomycin C in lung cancer.
Bronchial artery infusion of mitomycin C might be very effective in treating minor tumors but, as a rule, less effective in the treatment of larger tumors. In order to achieve improved effect of treatment, 21 cases (stage II-III/TNM) were given supplementary chemotherapy with bleomycin or vincristine-bleomycin. Preoperative treatment was given to 11 cases in which indications for surgical treatment were primarily uncertain or absent. The other group consisted of 10 patients with inoperable lesions. Combined treatment has proved to have a strong but mainly local effect. Repeated courses (up to 5 times) were more effective than a single one. The regional effect, i.e: on overgrowth onto the mediastinum, pericardium or thoracic wall was weak. The system effect was negligible. Penetrating data about objective response are given.

[Florid oral papillomatosis. A contribution to cytostatic therapy].
Based on the recent clinical experience in treating florid oral papillomatosis (FOP), the only successful therapy appears to be the use of cytostatic agents. The case report of a patient with clinically and histologically confirmed FOP is described to emphasize the advantages of administering Bleomycin intra-arterially (external carotid artery) by means of a Holter catheter. This catheter is used to release pressure in the treatment of internal hydrocephalus and is designed to remain in place for a number of years. The successful treatment of FOP points out the possibility of employing a Holter catheter for administering cytostatic agents in the treatment of malignant neoplasms in the facial area. Cytophotometric examinations of the prickle cells within the FOP mass showed a diploid pattern of DNA distribution similar to that of benigh tumors. However, it is not possible to definitely establish the malignant or benign nature of FOP in this manner.

Superficial anastomoses of blood vessels in the human heart.
We investigated superficial interarterial, intra-arterial, arterio-venous and veno-venous anastomoses in 100 hearts from men and women taken at random who died at 20-85 years of age. By means of careful dissection and injection into the blood vessels of a differently stained 12% solution of vinilit in acetone, we studied the number and localization of the anastomoses and their appearance. Interarterial anastomoses, i.e. anastomoses between the ramification of the left and the right coronary artery, were detected in 33 hearts. Intra-arterial anastomoses, i.e. anastomoses between the ramifications of one and the same artery, were seen in 5 hearts. Arterio-venous anastomoses were found in 39 hearts. Veno-venous anostomoses were found in 49 hearts. The veno-venous anastomoses display a great many variations, being commonly the regular finding in human veins.
Tricyclic antidepressant drugs as antagonists of muscarinic receptors in sympathetic ganglia.
Close arterial injection of McN-A-343 into the superior cervical ganglion of the cat resulted in contractions of the nictitating membrane. The ganglionic effects of McN-A-343 but not those of DMPP were antagonized in a dose-related manner by 2-10 mug of desipramine, imipramine, chlorimpramine, iprindole and viloxazine. No correlation was found between the dose of each drug which blocked the effects of McN-A-343 and that required to potentiate the responses of the nictitating membrane to intra-arterial administration of noradrenaline. It is concluded that clinically effective antidepressant agents can block muscarinic receptors in neural tissue, even if they do not do so in smooth muscle and gland cells.
