In this study, we tried to estimate the effectiveness of the antimicrobial activity of photodynamic therapy (PDT) without the destruction of tumour cells. Chlorin e6 in concentrations from 0.05 to 1.0 µg/mL and total dose of light 100 J/sq.cm were used. Samples from different tumours were tested for a presence of bacteria. Next, cells from the same tumours were treated with chlorin e6-PDT, chlorin e6, and light alone, or not treated. The survival rate was counted, and the cells were injected back into the animals. PDT caused the eradication of bacteria such as Proteus sp., Streptococcus α-haemolyticus, and others: the specimen became aseptic. After Ce6-PDT treatment and in control groups, tumour growth was observed in all rats 7-10 d after transplantation. The tumours were palpable and macroscopically visible. Our studies showed that PDT kills bacterial flora without the destruction of tumour cells. Thus, tumour cells free of bacteria could be used for other experiments.

The aims of our study were to assess the release of cytotoxic nucleoside analogs 5-fluorouracil and 2-chloro-2-deoxyadenosine from different lactide-glycolide or lactide-caprolactone biodegradable copolymers and the effects of sterilization on this release. The polymers were sterilized either with ethylene oxide at 37°C, or with gamma radiation (15 kGy, 20 kGy, or 25 kGy). The kinetics of nucleoside release from the copolymers were measured over 50 days. Four copolymers exhibited relatively constant release of nucleosides in micromolar concentrations during the entire observation period. Sterilization with either ethylene oxide or gamma radiation only slightly influenced nucleoside release. Further development of these copolymers as an intracerebral nucleoside delivery system for local treatment of brain tumors is indicated.

Str faecalis with respect to its thermal stability is used for evaluation of the pasteurization effectiveness in canned meat. In this work conventional doses of heating expressed as P (Tₒ=72°C, z= 10°C) required for sterilization of luncheon meat contaminated with Str. faecalis (10⁶ cfu) and containing various concentrations of NaCI (2, 3 and 3.5%) and starch (2, 4 and 6%) were determined. The relation was described as follows: y = 6.242 - 0.997 where r = -0.9549. The heat doses expressed as P = 5 min and P = 10 min assured pasteurization of canned meat at aw ≥ 0.985 and 0.955 to 0.972, respectively. Theoretical calculations indicate that pasteurization value P = 6.26 min assures sterilization of the examined tins.

A properly designed control system for canned-food sterilization is able to achieve the final desired level of bacterial inactivation, irrespective of any disturbances, e.g. in the form of undesired changes of the heating-medium temperature, and with a minimum of over-processing. The feed-forward control system for canned-food sterilization was described in the article.The controller in such a system is able: (a) to anticipate the change of the final cumulative lethality in a situation when the disturbances of the process occurred during heating and (b) to take appropriate corrective actions that can eliminate such disturbances. The heating turn-off decisions in such a controller are based upon the prediction (in every second during heating) of cumulative lethality for the cooling stage. The prediction of the cooling phase is based on a simulation of temperature changes in the coldest point inside a can using the empirical m-th order step-response model.

Nasiona lędźwianu siewnego odmian Derek i Krab, o zawartości suchej masy na poziomie około 33%, wykorzystano do produkcji mrożonek i konserw sterylizowanych. W surowcu świeżym i blanszowanym oraz produktach finalnych po 6 miesiącach przechowywania oznaczono zawartość: suchej masy, cukrów prostych i cukrów ogółem, skrobi, błonnika pokarmowego, azotu ogółem i azotu białkowego, składników popiołu, kwasów ogółem oraz poziom kwasowości czynnej (pH). Nasiona obu odmian charakteryzowały zbliżoną zawartością analizowanych składników, za wyjątkiem cukrów i skrobi. Blanszowanie nasion obniżyło poziom cukrów i składników popiołu. Konserwowanie i przechowywanie produktów oraz obróbka kulinarna mrożonki spowodowały ubytki wszystkich badanych składników. Stwierdzono, że ugorowane mrożonki, w porównaniu z konserwami sterylizowanymi, były zasobniejsze we wszystkie analizowane składniki. W ocenie sensorycznej, ugotowane mrożonki i konserwy sterylizowane z odmiany Krab uzyskały wyższe noty w porównaniu z odmianą Derek.
