The objective of this work was evaluate through different radiograph
techniques (retro alveolar bisectal, parallaje and parallelism)
all the information about lower third molars’ root structure. Those
techniques were performed to seven patients. Only one observer
did the inform: total number of roots; number of mesials’ roots;
curvature of mesials’ and distals’ roots; and disposition; between
all the Rx techniques previously named. The results show that with
the bisectal and the orthoradial technique, 71,4% of the lower third
molars observed had two roots; when modifying the horizontal
angulations of the central ray, 42,9% of the roots were fusioned
and the 57,1% were separated. With the orthoradial technique, and
the one varied from mesial and distal, 28,6% of the roots were
fusioned and 71.4% were separated. For mesials roots, with bisectal
and Orthoradial technique, 57,1% had only one root, and the 42,9%
left had two roots, but when modifying the angulations from mesial
and distal, 85,7% had one root, and 14,3% had two roots. Conclusion:
A higher percentage of cases where roots are separated is
observed when modifying the angulations of the central ray in
parallaje technique and it also improves the visualization of mesial’s
root curves, all very useful parameters to predict the kind of difficulties
the surgeon could face during surgery.

The Aloes had been used along the human history until our days in
several sicknesses. The aim of this work is detach the aloe medicinal
values and its popular uses, just as a first approximation to later
chemistry and botany studies. A search on bibliography, the most
common uses at folk belief was asked using semi structured interview
at people, dermatology doctors about the way they prepare
the aloe and the results obtained. The two principal products obtained
from the Aloe are: the acíbar and the gel, which are very
different between themselves, as chemical, pharmacology as therapeutic
point of view. The most common Aloe preparations have a
great medicinal value demonstrated by the tissue regeneration at
dermal level results. People obtained excellent results in radiation
cases, in skin dryness, allergies, insect’s bites or nettle. The application
of fresh leaves mitigate the irritation. Eating pieces of fresh
leaves, calm the digestive acidity, at internal uses of Aloe, it is very
difficult demonstrate its efficiency, like in asthma, rheumatic pain,
anemia, kidney infections, cancer, etc. It is very efficient in digestive
disorders and ulcer gastric. The problem in chronic or internal
disease is that the patient does not use only Aloe therapy, but several
at once. This is a first approximation about the Aloe uses in
popular medicine.

It was studied the antagonistic action between Rhodotorula glutinis,
and pathogenic fungi of lemon: G. candidum, F. moniliforme, A.
clavatus, P. expansum and P. digitatum. Were made solid assays to
evaluate the existence of antagonistic action. A suspension of R.
glutinis (1 x 10 8 UFC/ml) was dispersed all over the surface of
Sabouraud plates, after 1 h at room temperature, was carry out in
the center of the plate a hole, it was filled with 20 ul of phytopathogenic
fungi (1 x 10 4 spores/ml). The plates were incubated during 5
days at 28°C, after this time the percentage of inhibition of phytopathogenic
growth was evaluated. In presence of R. glutinis was
observed a total inhibition of G. candidum growth, (sour rot). There
was also a total inhibition of F. moniliforme growth (saprophytic
fungi of lemon), that produced a cotton-like material and gave bad
aspect to fruits. The growth of A. clavatus, P. expansum and P.
digitatum (green mold) was inhibited among 75-80%. Our next
objective will be determinate the mechanism of action of this
biocontrol agent.

It was studied antifungic action of Bacillus spp. metabolites (BM)
by in vivo assays. Assay A: We worked with 3 lots of lemons. The
first lot had farmy lemons (without any treatment), second lot had
lemons treated with NaHCO 3 ,hot water and synthetic antifungic
agentes (SAA). In third lot were lemons treated with NaHCO 3 , hot
water and BM. Assay B: We worked with four lots of lemons. The
first lot had lemons with NaHCO 3 , hot water, SAA and wax. The
second lot had lemons with NaHCO 3 , hot water, SAA and wax.
The third lot had farmy waxed lemons and in the last lot had lemons
treated with BM and wax. All lemons were placed in boxes.
All boxes were placed 3 weeks at 4°C and them one week at room
temperature. The % disease was determinated at 7 – 30 days.
In assay A the lemons treated with BM were infected 30% and the
disease of farmy lemons were 100%. In assay B the lemons treated
with BM were infected 20% while 90% disease of farmy lemons
were observed. In both assays the % disease of lemons treated with
SAA was 0-1%. It was demonstrated that wax have an protective
effect, because the % disease saw in assay B was lower than the
observed in assay A. These results are accord with the obtained,
previously, in vitro assays.
