The Authors show the results of a clinical trial carried out on two groups of patients affected by acute periodontitis. Patients were treated with proglumetacin or ketoprofen, respectively; the efficacy and tolerability of these two drugs were analyzed.

A Toxoplasma gondii genomic library was constructed in lambda EMBL3. Repeated fragments were detected by hybridization with radiolabeled total DNA from the parasite and one recombinant was chosen due to its strong hybridization signal. By using electrophoretic and hybridization analysis, four cross-hybridizating restriction fragments were selected and sequenced. The determined nucleotide sequence of these fragments (TGR1A, TGR1E, TGR2, and TGR4) has shown a complex system of conserved and degenerated repeats in which TGR1E corresponds to the most conserved element. This last sequence was used to investigate restriction fragment length polymorphisms among several T. gondii strains by Southern blotting.
Homologous sequences of the acute RNA tumor virus oncogenes have been found to be highly conserved within vertebrates, insects and yeasts. In the present work, seven different oncogene DNA sequences have been used as probes to search for homologous sequences in the DNA of the protozoan Plasmodium falciparum. Both the v-fms v-Ha ras probes hybridized P. falciparum DNA. The oncogene study will allow an understanding of the biology of the parasite and particularly the host-parasite relationships which allow P. falciparum to develop, keeping the established harmony between the parasite and his host.

The structural and functional connection between stomatognatic system, rachid, pelvis and lower limbs are well known; it's obvious that an alteration in one of these districts influences the other ones. Rolfing and applied kinesiology, on this ground, work to resolve muscular pain in cranio-cervicomandibular syndrome.
The Authors show two neuromuscular release methods employed in the treatment of cranio-cervico-mandibular syndrome; these methods work at the place of origin of the pathology resolving the symptoms in different districts of the body.

The diagnostic accuracy of the standard electrocardiogram (ECG) in apical myocardial infarction (MI) was evaluated in 112 consecutive patients with recent MI and wall-motion abnormalities limited to the left ventricular (LV) apex on two-dimensional echocardiography, performed at rest 21 to 84 days after MI. The following patterns of abnormal (greater than or equal to 30 ms) Q waves were found: anteroseptal (Q V1-V4) in 44 patients (39.3%), anterolateral (Q V1-V6 and/or I, aVL) in 22 (19.6%), inferior (Q III, aVF or II, III, aVF) in five (4.5%), lateral (Q I, aVL and/or V5-V6) in five (4.5%), anteroinferior in six (5.3%); non-Q MI was present in 30 patients (26.8%). By applying various proposed ECG criteria, the presence of apical MI was correctly identified in very few (24, 21%) patients. LV apex was extensively asynergic in 85 patients (76%) and partially asynergic in 27 (24%). All the patients with Q waves in lateral leads and 47% of the patients with non-Q MI had partially asynergic LV apex, while in the other ECG patterns, extensively asynergic LV apex was predominant. The presence of both greater than or equal to 30 ms Q waves and loss of R in left precordial leads and I strongly suggests extensive apical asynergy; normal QRS in the same leads, however, does not exclude extensive apical involvement.(ABSTRACT TRUNCATED AT 250 WORDS)
Using immunofluorescence techniques and flow microfluorometry analysis, we have demonstrated that the binding of a monoclonal antibody (VD5/25) produced against GP65, the major surface antigen of Leishmania braziliensis, increased on the surface of stationary-phase promastigotes from all the New World Leishmania species causing mucocutaneous or cutaneous disease as compared with the log-phase parasites. In addition, a sequential development of Leishmania amazonensis promastigotes from a non-infective to an infective stage was demonstrated. Indeed, promastigotes in the stationary phase (days 6-7) were found to be far more infective than those in the logarithmic phase of growth (day 3) both in vitro for mouse peritoneal macrophages and in vivo for BALB/c mice. The intracellular survival and multiplication of L. amazonensis were significantly inhibited when infective promastigotes were treated with the VD5/25 monoclonal antibody. The increasing expression of GP65 on the promastigote surface may thus contribute to Leishmania infectivity. This seems to represent a characteristic mechanism applicable to all New World Leishmania species studied.

The value of 12-lead electrocardiogram (ECG) and two-dimensional echocardiography (2D-ECHO, wall motion abnormalities) in recognizing myocardial infarction due to left circumflex and right coronary artery disease was evaluated in 75 patients (aged 26-69 years, within 3 months of myocardial infarction) with single vessel disease (luminal stenosis greater than or equal to 70%). Twenty-five patients (pts) had left circumflex disease and 50 right coronary artery disease. In the group of pts with left circumflex disease, 13 (52%)--group I--showed asynergy limited to the postero-lateral wall and 12 pts (48%)--group II--had more extensive asynergy involving both the postero-lateral and the infero-posterior wall. No pts with left circumflex disease demonstrated asynergy of the interventricular septum. Good correlations were found between the site and extent of asynergy and the location of left circumflex narrowings: 9--group I pts--(69.2%) had obtuse marginal branch disease and 8--group II pts--(67%) had proximal left circumflex disease. Patients with right coronary artery disease were subdivided as follows: group I: 35 pts (70%) with asynergy of infero-posterior wall and posterior septum; group II: 11 pts (22%) with extensive asynergy of infero-posterior, postero-lateral walls and posterior septum; group III: 4 pts (8%) with asynergy limited to the infero-posterior wall. The location of right coronary artery narrowings had no relation to the site and extent of infarct asynergy in pts with single right coronary artery disease.(ABSTRACT TRUNCATED AT 250 WORDS)
